editor’s note

This magazine isn’t I have edited this magazine for many years but this is the first time I have had an ‘editor’s comment’ space. So I thought I would start by explaining what this magazine isn’t. It isn’t a journal. There are thousands of scientific journals being published, ScienceDirect lists 3377 of them, but there are many more than this. Whatever your area of interest or expertise, you can be assured of finding a journal that covers the area. In fact, you’ll probably find a plethora of them from the high-impact, peer-reviewed to the one-man band with a private agenda. Each scientist can be defined by the journals they subscribe to; it is highly unlikely that the molecular spectroscopist studying the electron states of radicals in extra-terrestrial bodies subscribes to a single magazine in common with the quality assurance manager in a butter factory. And neither of them gets the same magazine as the research geneticist. Often there would only be a handful of people receiving a particular journal in Australia and New Zealand. But this magazine isn’t a journal. It is a very simple overview of what is new out there and where you can go to find out more. The main focus is on equipment and services suitable for use in laboratories or, as diagnostics move closer to the factory line or patient, by laboratory personnel. The information given is hopefully enough for you to determine if the item is of interest to you, but there is no way it tells the whole story. If you are interested, it should point you in the direction of the manufacturer or Australian/New Zealand distributor who will be able to tell you the whole story. On our website,, there is a directory where all of the new products and services covered in the magazine plus more can be found in a searchable format. If you know what you want, you will be able to find manufacturers and distributors. However, if you don’t know something exists you can’t search for it - that’s where the magazine comes in. This also explains the “What’s new” part of the magazine title! I hope you find the magazine useful for what it is - a quick and handy resource keeping you up to date with products and services with some general interest articles as an added bonus. I am always happy to accept material for consideration for inclusion in the magazine or any feedback - so don’t be shy, send me an email at

Australian marine research will be boosted in 2013 with the delivery of a new research vessel that will carry up to 40 scientists on every journey.


or 40 years, the Southern Surveyor - the research vessel of the Marine National Facility - has conducted scientific voyages covering everything from underwater volcanoes to a carbon chemistry map of the Great Barrier Reef. But soon, it will be replaced with a new vessel, one in which the Australian Government has invested $120 million - the RV Investigator. The Investigator was purchased for the Future Research Vessel Project, launched in 2009 as part of the government’s Super Science Initiative. Like the Southern Surveyor, it will be owned and managed by the CSIRO, which also operates the Marine National Facility. It is hoped that the new vessel will meet the needs and answer the questions of an ever-expanding scientific community - especially those related to climate change - while also providing a more efficient, advanced alternative to the Southern Surveyor. At 93.6 m in length, it will be able to hold more scientists, have longer voyages and be operational for twice as long as its predecessor. It will be capable of operating continuously for 60 days at sea, cruising at 12 knots over a range of 10,000 nautical miles each voyage. But the Investigator’s own journey has only just begun. Having started construction on 31 January in Singapore, it will not be delivered to Australia until June 2013, at which point 80% of the interior will have been fitted out. The remaining equipment will be fitted here, with some of it to be transferred from the Southern Surveyor. A testing period will then run for the next few months, finishing towards the end of the year. The vessel will contain scientific equipment worth $20 million, including a core backbone of permanently fitted sampling, data acquisition, management, presentation and communication systems - all of

which will be available to any research team using the vessel. Teams will be able to add systems to support their own investigations as well, such as radiation and trace metal laboratories; deep-water dredging, coring and drilling devices; fishing nets; towed camera systems; and remotely operated vehicles. The vessel will also, for the first time, include a two-tonne Bureau of Meteorology radar and accompanying equipment. It is this which interests Melita Keywood, an atmospheric scientist who works for the CSIRO and Bureau of Meteorology. Keywood has never been on a research vessel before, mainly due to the fact that an Australian vessel has never before had the facilities for atmospheric research. Having this equipment on board will allow her to conduct examinations which were previously only possible on land. “What’s new about the RV Investigator is that we now have laboratories on the ship that are just really there for us to install our equipment in,” says Keywood. “And also, the way we get the air from the atmosphere into the ship is really important, so we’ve had to design special sampling inlets for that.” Keywood’s research, which will take her from the Southern Ocean to the Timor Sea and the Great Barrier Reef, will focus on gathering data on the atmosphere of the Southern Hemisphere. She explains, “The Southern Hemisphere is much cleaner than the Northern Hemisphere. We have a lot less sources of pollution in the Southern Hemisphere. Often that means we get ignored. So if you look at climate models, or if you look at observation networks, you’ll see that there’s not a lot of data or information coming from the Southern Hemisphere. “The main thing that the RV Investigator is going to allow us to do is to make




This gives you an idea of what the RV Investigator will finally look like.

these measurements and to fill up that database of what’s going on in the Southern Hemisphere, so that when people run their climate models for the globe, they have some data they can use.” Just like any Australian scientist who wants to use the Investigator for research, Keywood had to submit an ‘expression of interest’. The Marine National Facility examines each proposal for its scientific merits, then comes up with a series of destinations for the project’s voyage. Research teams can even piggyback’ with other groups that wish to go to the same area at the same time of the year, as the Investigator can accommodate up to 40 scientists, while the Southern Surveyor could only hold 15. “It’s going to be pretty rare that you could get 40 people on one project,” says Keywood. “There’s going to be a need to combine several different projects in one voyage.” Just as the research projects are nominated and selected, so too is the equipment that each party uses. Keywood is a member of the Technical Advisory Group (TAG), whose role is to select this equipment. The TAG does this by approaching each research community and


asking them what equipment has to be on the ship in order to provide the data they need. The TAG then comes up with a list of priorities based on these results. It is clear that the Investigator will have a big impact on Australia’s scientific opportunities. Despite having the third largest ocean territory in the world, Australia is actually under-resourced when it comes to marine research. Keywood explains, “If you compare the territory of water that Australia covers, it’s very similar to Canada. Canada has 17 research vessels like this, and Australia has one. But if you compare somewhere like Belgium, which is very small, they have three vessels. So we’ve actually got fairly minimal resources for the amount of area of sea that surrounds Australia. “Having said that though, you’ll find that it means we’re a lot more efficient at what we do. A lot of the publications that come out of the research of the Southern Surveyor are top notch, and they’re recognised as some of the best in the world. So I think that we do very very well considering the resources that we have. “Now the Investigator, in terms of people, and time at sea, is going to triple the amount of material that we can collect


and the amount of data we can collect.” This, claims Keywood, will allow for a more collaborative approach - both interdisciplinary and international. “You can imagine, the Southern Ocean is very difficult for someone from North America or Europe to get to, so if they can have access to our ship that’s going to be very attractive for them to be involved in our research. And that’ll only make our research even more useful and more high quality.” So while the RV Investigator’s maiden voyage is still a long way away, Keywood is excited for the role the vessel will play in the world of marine and atmospheric research. “It’s really opened up the scope for the science that we do in our group at CSIRO,” she says. “I think it’s really an exciting development for us, and hopefully we’ll be able to utilise it in the best possible way and get the most out of it.” With thanks to Melita Keywood and Sarah Schofield (Communication Officer - CSIRO Marine and Atmospheric Research).

EDXRF analysis of sulfur in oil by ASTM D4294 Applied Rigaku Technologies has announced the publication of an application note for the analysis of sulfur (S) in oil per ASTM D4294. Application Note #1135 demonstrates the efficacy of the Rigaku NEX QC benchtop energy dispersive X-ray fluorescence (EDXRF) analyser for this measurement. Sulfur will always be an important element in crude and fuel oils, and plays a significant role in fuel quality as well as in the control of polluting emissions. Worldwide, regulations limit allowable sulfur content in diesel fuels, kerosene, heating oils and similar fuels. Jet fuels also rely on the measure-

Mitochondrial dysfunction precedes memory loss in Alzheimer’s disease Brian Kilen


itochondria - subunits inside cells that produce energy - have long been thought to play a role in Alzheimer’s disease. Now, Mayo Clinic researchers using genetic mouse models have discovered that mitochondria in the brain are dysfunctional early in the disease. The findings appear in the journal PLoS ONE. The group looked at mitochondria in three mouse models, each using a different gene shown to cause familial, or early-onset, Alzheimer’s disease. The specific mitochondria changes corresponded with the mutation type and included altered mitochondrial movement, structure and energy dynamics. The changes happened in the brain even before the mice showed any symptoms such as memory loss. The group also found that the mitochondrial changes contributed to the later loss of mitochondrial function and the onset and progression of Alzheimer’s disease. “One of the most significant findings of this study is our discovery of the impact of mitochondrial dysfunction in Alzheimer’s disease,” says Eugenia Trushina, PhD, Mayo Clinic pharmacologist and senior investigator on the study. “We are asking: can we connect the degree of mitochondrial dysfunction with the progression of symptoms in Alzheimer’s disease?” Enlisting the expertise of Mayo researcher Petras Dzeja, PhD, the team applied a relatively new method called metabolomics, which measures the chemical fingerprints of metabolic pathways in the cell - sugars, lipids, nucleotides, amino acids and fatty acids, for example. It assesses what is happening in the body at a given time and at a fine level of detail, giving scientists insight into the cellular processes that underlie a disease. In this case, the metabolomic profiles showed changes in metabolites related to mitochondrial function and energy metabolism, further confirming that altered


mitochondrial energetics is at the root of the disease process. The researchers hope that the panel of metabolomic biomarkers they discovered can eventually be used for early diagnosis, treatment and monitoring of Alzheimer’s progression. “We expect to validate metabolomic changes in humans with Alzheimer’s disease and to use these biomarkers to diagnose the disease before symptoms appear - which is the ideal time to start treatment,” Dr Trushina says. The team looked at neurons of three different genetic animal models of Alzheimer’s disease. Researchers applied a mitochondria-specific dye and observed their motion along axons, a process called axonal trafficking. They showed that even in embryonic neurons afflicted with Alzheimer’s disease, well before the mice show any memory loss, mitochondrial axonal trafficking is inhibited. Using a panel of techniques that included electron and light microscopy, they determined that in the brains of mice with Alzheimer’s disease, mitochondria tended to lose their integrity, ultimately leading to the loss of function. Importantly, dysfunctional mitochondria were detected at the synapses of neurons involved in maintaining memory. “We are not looking at the consequences of Alzheimer’s disease, but at very early events and molecular mechanisms that lead to the disease,” Dr Trushina says. The next step is looking at the same mitochondrial biomarkers in humans, she says. As the researchers begin to understand more about the mitochondrial dynamics that are altered in Alzheimer’s disease, they hope to move on to designing drugs that can restore the abnormal bioenergetics and mitochondrial dynamics to treat the disease.

Magnificent microbes The 2012 Australian Society for Microbiology Annual Scientific Meeting will showcase the importance of microbiology to our world through presentations delivered by national and international leaders in their disciplines.


rofessor Ian Frazer needs no introduction. His work in immunology, culminating in the development of the HPV vaccine against cervical cancer, earned him the titles of the 2006 Queenslander of the Year and Australian of the Year. His current research interests include immunoregulation and immunotherapeutic vaccines, for which he holds research funding from several Australian and US funding bodies. It is this research which Professor Frazer will be speaking about at the 2012 ASM Annual Scientific Meeting. This large and prestigious microbiological conference, to be held over four days, will bring together researchers, clinicians, professionals and supporters from all microbiological disciplines. It will be held at the Brisbane Convention and Exhibition Centre, which is within easy walking distance of the Brisbane River and the CBD. The scheduling of the conference has been designed to provide delegates with a richer, more concentrated experience, which also provides the time and opportunity for networking. Professor Frazer will present the prestigious Rubbo Oration, to be held on the third day of the conference, while a range of plenary lectures by world leaders in medical and veterinary microbiology, applied and environmental microbiology, virology and molecular microbiology will also be delivered over the course of the event. Symposia, other oral and poster presentations, and workshops round out the program.

Plenary speakers Jill Banfield Jill Banfield is a geomicrobiologist whose work focuses on the relationship between microorganisms and their chemical environments, most notably minerals. Her work has helped us understand

How to clean up your meth lab


eveloped more than a decade ago and used to decontaminate US federal office buildings and mailrooms during the 2001 anthrax attacks, Sandia’s decontamination foam is now being used to decontaminate illegal methamphetamine labs. Mark Tucker, a chemical engineer in Sandia’s Chemical & Biological Systems Dept. and co-creator of the original decontamination foam, said it renders all types of typical chemical and biological agents harmless. “For structures contaminated with meth, owners have two choices: demolish it or reclaim it,” said Kevin Irvine, vice president and general manager at EFT Holdings, which licenses the Sandia formulation and sells it under two names, EasyDecon DF200, certified against chemical and biological agents, and Crystal Clean, intended for meth cleanup. The meth clean-up problem is a big one. The U.S. Drug Enforcement Administration’s (DEA) Clandestine Meth Lab registry lists thousands of locations in the U.S. where law enforcement agencies have found chemicals or paraphernalia indicating the presence of either clandestine drug laboratories or dumpsites. In 2007, EFT released Crystal Clean, a chemically identical formula to EasyDecon DF200, but packaged and marketed specifically for meth clean-up. Sites contaminated with meth are considered crime scenes, but the contamination is chemical rather than biological. The approximately 700 remediation companies that clean up meth lab contamination also do other types of crime scene clean-up because they are accustomed to the sampling and documentation process.

Holding the bag “Property owners are often liable for expensive clean-up costs since most insurance companies won’t pay for clean-up related to methamphetamine, viewing damage resulting from meth labs

as arising from a criminal act,” Irvine said. “That means that property owners and landlords are often left holding the bag for the cost of remediating a residence or business contaminated as a result of meth cooking.” According to the Department of Justice, the chemicals used to cook meth and the by-products from its manufacture, produce toxic fumes, vapours and residues. The report said anyone exposed to these by-products, especially children, could suffer short- and long-term health problems. Prolonged exposure to meth by-products may cause cancer; damage the brain, liver, kidney, spleen and immunologic system; and result in birth defects. Tucker said many cleaning methods don’t remove methamphetamine and the chemicals used to produce it. Incompletely or improperly cleaned surfaces, such as floors, countertops and drywall, can remain contaminated for months or even years, even after many clean-ups. Sandia’s decontamination formulation includes a collection of mild, nontoxic and noncorrosive chemicals found in common household products, such as hair conditioner and toothpaste. It contains both surfactants, which lift agents off a surface, and mild oxidizers, which break down the agent’s molecules into nontoxic pieces that can be washed down a household drain like detergent or dish soap.

Formulation left meth non-detectable In experiments from a few years ago, John Martyny, associate professor and industrial hygienist at the National Jewish Medical and Research Center’s Division of Environmental and Occupational Health Sciences and a national expert on the effects of meth exposure on children, compared the effectiveness of common cleaners, such as detergent and bleach, on methamphetamine clean-up. Martyny included Sandia’s decontamination formula in the testing. His experiments showed that, after cleaning with




EasyDecon, the methamphetamine present on tested surfaces was likely oxidised to another compound and was non-detectable. Irvine said even if a meth site is known, it doesn’t always mean it gets cleaned up, due to the expense. Some states don’t have clean-up guidelines and don’t require homeowners to disclose whether a structure is contaminated with meth. Some families have discovered they were living in a house contaminated with meth only after family members were hospitalised for respiratory problems characteristic of chronic meth exposure. In the 22 states that have guidelines, structures contaminated with meth are seized by police and the structure is quarantined by a local or state agency (depending on the state) until the structure is proven cleared of methamphetamine to a certain level. During structure remediation with Crystal Clean, a remediation crew removes everything from the structure, including carpets and drapes, until the house is stripped bare except for the fixtures. The crew mixes the Crystal Clean solution on site and sprays the foam on walls, ceilings and floors. The foam expands to about 15 times its liquid volume through a special nozzle that draws air into the spray, allowing it to reach contamination in crevices and in the air. In an hour, it collapses back to a liquid. Using only fresh water, rags and sponges, the crew then removes the benign residue from all surfaces.

After the site is cleaned, an independent industrial hygienist tapes off a sample area in the cleaned structure and takes a number of swipe samples appropriate for the location size. The samples are treated as evidence, a formal chain of custody is established and they are taken to an independent lab. The lab runs the samples through a mass spectrometer to determine the level of contamination. In most instances, Crystal Clean reduces the levels to .02 µg/100 cm2 or less, which is considered non-detectable. Irvine said the Crystal Clean formula is more expensive than other cleaners, but it saves greatly on labour costs and lab costs because other cleaning solutions usually require more than one cleaning, with a larger crew doing the cleaning and with costly sampling taking place in between cleanings. Another advantage of this clean-up method, Irvine said, is that some other methods are destructive or use more corrosive substances and the resulting chemical residues are themselves toxic. Crystal Clean is rendered nonhazardous and nontoxic, requiring only a surface wipe when finished. Sandia’s decontamination formula was developed with funding provided by the DOE and NNSA Chemical and Biological National Security Program (CBNP). Sandia has also licensed the DF200 formula to other firms, which have developed it for use in a variety of applications, such as commercial and residential mould remediation, disinfection of hospitals and schools, pesticide removal for farm equipment and military applications, including counterterrorism preparedness. The foam also has been deployed as a preventive measure at presidential debates and a political convention. Sandia National Laboratories

Bespoke analytical technology platforms improve testing process A successful collaboration between automation systems developer Astech Projects and a research-based pharmaceutical and healthcare company has been detailed in the poster ‘Technology Implementation for Analysis of Inhaled Products’. Having been recently presented at the Drug Delivery to the Lungs (DDL) conference and exhibition, the poster details how bespoke analytical technology platforms in support of dry powder inhaler (DPI) testing have been implemented within the GlaxoSmithKline (GSK) inhaled testing laboratories using a quality by design approach. The process has been summarised below.

Novel Emitted Dose (nED) The dry powder inhaler (DPI) nED is a manual apparatus that recovers the emitted dose from DPI devices. During the emitted dose test, a DPI device is primed and clamped into a firing station sealed to a DPI Dose Collector and an airflow drawn through the device via a critical flow controller. The collected dose is recovered via a washing station by pumping solvent through the dose collector into a volumetric flask for analysis. Drying and re-preparation is performed using a Dose Collector Drying Station. This technology greatly improved robustness of the testing and reliability of data as well as delivering a much more efficient and cost-effective procedure over the manual procedure.

Blister Sampling Apparatus (BSA) The BSA facilitates the recovery of powder blend from single blisters from a DPI strip for either the content uniformity or bulk assay procedures. The DPI strip is clamped onto the BSA, the blister is punched out of the strip and pierced before metered solvent is dispensed from a solvent reservo through the blister and delivered into a recovery flask for processing and analysis. This system meant that significantly more data points could be generated in a safer, costeffective and more reliable way.

Next Generation Dose Sampling Introduction (NDSI) The NDSI system automates either waste firing or collection of the powder within the Next Generation Impactor (NGI). The device holder is identical to that on the AED (see below) and nED and thus minimises any potential variability in the sealing of the device to the NGI USP Throat. This system requires minimal human intervention and complements the NSRS, improving robustness of the NGI procedure.

Next Generation Impactor Sample Recovery System (NSRS) The NSRS is designed to quantitatively recover drug particles from the NGI with solvent and deliver the sample solutions into HPLC vials for analysis. The hardware has nine individual plumbing subsystems, each an isolated channel that recovers, collects and cleans a set of NGI collection cups and related components. The throat, mouthpiece, collection cups 1 to 7 and Micro Orifice Collector (MOC) are each rinsed with a single aliquot of solvent. Recovery method parameters are specified in the user-defined methods. All operations and events of the NSRS are recorded in the software database and can be printed in preformatted reports. Particle size distributions comprising all stages of the Impactor can be consistently generated both during product development and routine quality control.

Automated Emitted Dose (AED)

The AED fully automates the DPI product content uniformity test. Once the user loads the devices, appropriate solvents and initiates the correct program, the system will waste fire and collect the defined blisters. The collectors are rinsed with solvent and HPLC autosampler vials containing sample solution are prepared. With less human intervention, the risk of analytical error is significantly reduced.


In comparison to the manual procedures previously employed, the platforms increased throughput by substantially reducing the time taken to perform 100 samples and minimising analytical variability. In addition, use of the platforms decreased the volume of solvent needed for testing, reducing the waste streams and resulting in greener, more cost-effective testing.


Technology platforms have been implemented throughout the product development lifecycle, improving throughput, efficiency, safety and minimising analytical variability. The platforms form a strategy to support and justify product specifications and improve the science and understanding of inhaled products. They will be implemented across the GSK network as part of method/technology transfer prior to product, ensuring that the analysis of Inhaled products across the network is rugged and representative of the true quality of the product.

Modern bio-decontamination solutions

Bio-processing is presenting new challenges as the size and scale of operations increase. Maintaining clean facilities can be problematic as traditional methods of sterilisation become difficult to deploy in a controlled and regulatory compliant way.


he utilisation of mammalian or bacterial cell lines in the production of modern drug or cellular therapies represents a considerable challenge to the maintenance of clean facilities. The very conditions required for the growth, culture and maintenance of these cellular factories present an ideal environment for the accidental culture of extraneous, undesired biological contaminants such as viruses and microbes as well as material such as spores, fungi and mycoplasma. The increase in size and scale of bioprocessing also presents a challenge. Traditional methods of sterilisation such as steam and manual cleaning become increasingly difficult to deploy in large complex production areas in a controlled and regulatory compliant manner. Historically, production of classic small molecule drug products has predominantly been performed chemically, in an environment hostile to the presence and culture of most biological contaminants. Additionally, these products are commonly amenable to terminal gamma or steam sterilisation, ensuring the integrity of the product at the point of final packing or filling. Modern biopharmaceuticals present a multiple challenge when considering the need to present a safe and defined final product at the point of patient contact.

Nature of biological contamination Biological products are manufactured in complex production lines commonly involving seeding trains, bioreactors and numerous

clearing and filtration steps in order to produce the desired final product. A number of these production steps present opportunities for contamination to be introduced or even cultured alongside the desired cell line. The contamination may be critical to process integrity or may merely reduce cell titre in seeding. However, modern in-line process monitoring and recording has raised the challenge of maintaining critical parameters across a production line to ensure batch to batch consistency in order to meet increasing levels of regulatory compliance. Although a particular contaminant may be the specific cause for concern, a bio-decontamination method should ideally display broad spectrum efficacy against any potential contaminant, thus minimising the need for additional cleaning procedures. The commonly employed Geobacillus stearothermophilus biological indicators are representative of the most difficult classification of organisms to kill; they are bacterial endospores and thus act as a strong surrogate for evidence of deactivation of other biological entities.

Process control and monitoring Deployment of a bio-decontamination technique in these heavily regulated environments increasingly requires the use of controlled and monitored processes that, by definition, can be validated to ensure efficacy. This is in strong contradiction to the formaldehyde fumigation method of room and facility decontamination. This inherently uncontrolled and unmonitored process presents challenges




in generating data on actual contact times of the biocide with the environment as well as presenting a considerable risk to the health of staff, formaldehyde being recently classified by WHO as a human carcinogen.

largest production areas to be decontaminated as one cycle in a controlled manner, ensuring rapid 6-log sporicidal kill of any contaminated zones.

Material transfer

As transfer in and out of production areas comes under regulatory supervision and classical spray and wipe manual methods face the challenge of validation, Bioquell provides equipment for the rapid entry and exit of equipment and materials into and out of areas through whole solution material transfer products. Load presentation is critical to successful validation of these processes and represents a significant part of the validation procedure for material transfer solutions; validation of ‘worst case’ loads ensures confidence in this critical process.

Maintenance of clean room condition is inherently dependent on appropriate operator protection and a sizable effort is employed in ensuring the workforce minimises contaminants brought into monitored environments. Of equal concern is the movement of materials into and out of clean rooms, in terms of prevention of outside contaminants entering a cleanroom through, for example, maintenance equipment, monitoring equipment and support equipment. In many instances this equipment is not amenable to steam sterilisation, for example in an autoclave.

Proactive vs. emergency decontamination of a facility There are a number of both in-house and external benefits to carrying out a proactive decontamination, namely, the preparation of plans for facility decontamination are already in place so any emergency work required, following outbreak of contamination, can be deployed more rapidly. The ability to synchronise any scheduled maintenance downtime with a decontamination cycle also ensures minimisation of the risk of contamination of an area by any maintenance work while also ensuring bio-burden levels are proactively kept to an absolute minimum. From a regulatory standpoint, having a bio-decontamination plan in place prior to any outbreak reassures the regulator that the plan of action was put together in a defined and logical manner and prior validation of the efficacy of a cycle assists in demonstrating efficacy of decontamination.

Room/facility decontamination Over 20 years Bioquell has amassed expertise in the bio-decontamination of a wide range of facilities including hospitals, biomedical facilities, pharmaceutical production areas and bioprocess production facilities. This expertise coupled with the infinite scalability of Bioquell’s Room Bio-decontamination Service (RBDS) allows even the

Material transfer solutions

Validation The regulatory aspects of qualification (validation) generally relate to being able to prove, in a definitive way (typically by documented evidence) that: the equipment complies with the specifications; the critical parameters of the processes are under control; the process parameters are repeatable and there is adequate margin of safety in the process to take account of minor variations in the process performance or environmental conditions. Nothing can be assumed. Any read-across between results must be backed up by rationale, and of course all relevant data is recorded, signed and available in a suitable format. There are also requirements for training, standard operating procedures and methods of monitoring and taking corrective action as necessary.

Conclusion Hydrogen peroxide vapour represents a rapid, integratable technique for the residue-free, bio-decontamination of both routine and challenging areas within a biotech production facility whilst allowing maintenance of clean room integrity, protection of workforce and protection of product through integrated material transfer solutions.

Biological indicators

New Look

Biological indicators (BI) provide the best assurance of sterility by challenging the steriliser with quantifiable, highly resistant Geobacillus stearothermophilus spores. A system available from Arrow Scientific includes rapid readout biological indicators, disposable test packs, auto-readers and record keeping. Biological indicators are used for load

for 2012

control monitoring, which is the process by which a load is monitored and released based on the result of a biological indicator. Self-contained BI for 121°C gravity or 132°C vacuum-assisted cycles consist of a Bacillus stearothermophilus spore strip, sealed glass ampoule with growth medium and dual indicator system. After sterilisation, the vial is crushed to join the growth media with the processed spore strip. The BI is incubated for 3 h at 60°C in the Attest auto-reader for a fluorescent reading. A red light indicates an unambiguous positive result or sterilisation failure. The auto-reader, which is used with the rapid readout steam biological indicators, reduces quarantine time, allowing for quick and efficient detection of sterilisation process failure (1 to 4 h). The product is self-contained, reducing the risk of false positives due to contamination. It conforms to ISO 11138.

Protein quantitation system Merck Millipore has launched the Direct Detect system for rapid, simplified protein quantitation. The system enables infraredbased measurement of amide bonds in protein chains, an intrinsic component of every protein, without relying on amino acid composition, dye-binding properties or redox potential. Conventional assays based on UV-Vis spectroscopy rely on absorbance by a protein’s aromatic amino acids and therefore have limited utility. In addition to its analytical powers, the system provides a departure from traditional sample prep requirements typical of biomolecular quantitation. After samples are spotted on assay cards, they can be stored in ambient conditions without appreciable change in readout. Another advantage over conventional assays is that the Direct Detect calibration standard curve requires generation once, which provides additional time savings and ease of use. The system employs a hydrophilic polytetrafluoroethylene (PTFE) membrane designed to be transparent in most of the infrared spectral region and enables application of biomolecule solutions directly onto the membrane. The system delivers more universally applicable and faster protein quantitation, requiring minimal sample consumption. System accuracy and precision are comparable with results obtained by amino acid analysis, an accurate standard for quantitation, yet can be time consuming and often costly. Because the system relies on IR-based detection of biomolecules, users can obtain accurate and reproducible protein quantitation in presence of reducing agents and detergents. As a result, the system can measure protein concentrations from 0.2 to 5 mg/mL within seconds, without any bio- or immunochemical staining, directly from samples, including buffered solutions. The system can also be used to provide information on non-protein sample components, such as lipids and nucleic acids. Merck Pty Limited Contact info and more items like this at

Quality tissue cutting for Human Protein Atlas Project The Human Protein Atlas Project is using the Thermo Scientific HM355S automated microtome and Section Transfer System to create high-quality tissue sections during tissue microarray (TMA) production. As part of the project, and as an external TMA production service, the Uppsala-based Science for Life Laboratory (SciLifeLab) tissue profiling group has cut more than 200,000 slides from over 1400 TMAs to date. To achieve this, SciLifeLab required a versatile microtome that would accommodate a variety of tissue types, with a choice of manual and mechanised cutting. The HM355S met these needs. When sectioning TMAs, the greatest risk of valuable tissue loss or damage can occur during transfer to a water bath. For this reason, the SciLifeLab group uses the automated Section Transfer System alongside the HM355S to eliminate such risks. This 'waterfall' system stretches sample ribbons as they are cut and simultaneously transports them safely from the blade into the integrated circulating laminar flow bath. From here, sections can be readily mounted onto glass slides. The actual composition of a tissue array can also cause complications when sectioning. An example is cancer tissues, which are generally homogenous where normal tissues have greater heterogeneity. “To overcome issues with mixed tissue composition, our experts group tissues into those with similar texture and hardness when sectioning to make set-up easier and improve workflow,” explained Dr Caroline Kampf, SciLifeLab and HPA site director. “The HM355S microtome gives us the high-quality, reproducible sections that we need for analysing the TMAs. The different cutting modes provide greater control over section generation, which is especially useful when sectioning a range of specimens of differing consistency.” A further sectioning consideration at SciLifeLab Uppsala is the fact that the TMAs are paraffin embedded. Consequently, the Thermo Scientific Cool Cut peltier-cooled attachment is used on the group’s microtomes to prolong the cutting period by maintaining a cool block temperature. By using such a cooling tool, 50 TMA sections can be cut consecutively in 50 min without the need to remove and re-cool the block on ice. This ensures effective throughput and efficient laboratory operation. “Due to the enormity of profiling the human proteome, our team holds a great deal of practical experience in TMA production for the HPA and, in fact, we now offer an external TMA production, sectioning and scanning service,” said Dr Kampf. “Consequently, our experts handle many different types and combinations of tissues for which safe, efficient and high-quality sectioning, provided by the Thermo Scientific HM355S and associated attachments, is fundamental to our high-throughput, high-quality TMA production.” For more information, visit pathology and Thermo Fisher Scientific Contact info and more items like this at

Toppling Raman shift in supercritical carbon dioxide Vibrational mix shines new light on carbon sequestration measurements Just as a wine glass vibrates and sometimes breaks when a diva sings the right note, carbon dioxide vibrates when light or heat serenades it. When it does, carbon dioxide exhibits a vibrational puzzle known as Fermi resonance. Now, researchers studying geologic carbon storage have learned a bit more about the nature of carbon dioxide.


he results provide clues to the nature of the Fermi resonance in other molecules, and will help researchers better understand details in chemical reactions. The team of researchers from the Department of Energy’s Pacific Northwest National Laboratory reported their findings in the journal Physical Chemistry Chemical Physics. “We’re happy to be able to say something new about something so old,” said PNNL chemist and author Charles Windisch, Jr. “We figured out how the different carbon dioxide molecules are vibrating at some of the Fermi resonance frequencies. And, of course, we can calibrate our data with more accuracy now.” “Even to this day, people mark Raman spectra incorrectly,” said PNNL computational chemist Vassiliki-Alexandra Glezakou. “It helps to know what we are looking at, if we are going to use certain bands as guidelines to understand molecular interactions.”

called supercritical. To follow supercritical carbon dioxide in chemical reactions, researchers often use Raman spectroscopy. Raman spectroscopy is a way of capturing a molecule’s vibration. Simple molecules can vibrate in well-defined modes such as stretching and bending, which correspond to peak frequencies on a graph. These peaks are as unique and reproducible as a fingerprint. The number and position of these peaks in a spectrum can be predicted by quantum mechanics, but Fermi resonances result in unanticipated peaks due to a combination of two different vibrations, such as stretching and bending. First recognised in carbon dioxide and explained by Enrico Fermi in 1931, scientists agree that the Fermi peaks are the result of the mixing of the two vibrational modes, but they often label one of them as ‘stretch’ and the other as ‘bend’. This labelling became a problem when PNNL researchers observed a ‘flip’ in the Raman spectrum of supercritical carbon dioxide.

Carbon dioxide conundrum

Shift or flip?

The PNNL researchers did not set out to study again a phenomenon that dates back to the 1930s. Instead, they wanted to investigate what happens when carbon dioxide is stored underground as part of a national research effort to reduce carbon emissions from power generation. To do so, researchers plan to inject carbon dioxide in an unusual form of the gas that behaves like a liquid due to it being under high pressure,

To follow reactions, researchers often use different versions of elements called isotopes. Normally, carbon dioxide contains carbon plus the isotope oxygen-16, the most common form of oxygen. By using a heavier isotope of oxygen with its own fingerprint, oxygen-18, PNNL researchers can track the fate of carbon dioxide when it reacts with minerals, particularly when there are other sources of oxygen present such as water.

In the Raman spectra of the lighter supercritical carbon dioxide, the pair of Fermi peaks included a weaker one at a lower frequency and a stronger one at higher frequency. When they replaced all of the oxygens with the heavier isotope, however, the peaks seemed to flip, with the stronger one appearing at a lower frequency instead. At first, it was not clear how the two sets of Fermi peaks related to each other - whether the peaks were really a mirror image or if the stronger oxygen-16 peak somehow morphed into a weaker peak when heavy oxygen-18 was introduced. Typically, a heavier isotope will shift peaks to lower frequencies, although different modes are not necessarily affected by the same amount. The researchers needed to unambiguously identify the peaks and to figure out how much bending and stretching modes contributed to each one. To do so, the team decided to simulate the carbon dioxide molecules with different oxygen isotopes on a computer and see if they could recreate the Raman spectra they saw in their experiments.

To the computer Using computing resources at EMSL, DOE’s Environmental Molecular Sciences Laboratory at PNNL, Glezakou simulated carbon dioxide in supercritical conditions similar to those in the experiment. The molecules were ‘made’ with either oxygen-16 or oxygen-18. They analysed the motion of the molecules to produce computational spectra that echoed the real spectra.

In this way, the team was able to determine the percent of bending and stretching modes expected in each peak. The results showed that with oxygen-16, the stronger peak at the higher frequency is due mostly to the stretching mode, while the weaker peak at the lower frequency is due mostly to the bending mode. Oxygen-18, however, told a different story. The results with heavy carbon dioxide showed unequivocally that the light- and heavy-oxygen peaks were not exactly mirror images of each other. Carbon dioxide is mostly a linear molecule, so the bending motion is much less affected than the stretch when the oxygen-16 is replaced by its heavier isotope. As a result, the composition of the peaks does not remain the same. “The heavier oxygen doesn’t just shift the peaks. It changes their identity,” said Glezakou. “And the bigger effects are on the stretching, because the peak with the most stretching has the biggest frequency shift.” Windisch added that the experimental results matched the computational ones nicely, in spite of the difficulty. “Our colleague Paul Martin here at PNNL had to build equipment so we could do these experiments at the pressures we needed. Not easy,” he said. Having nailed down the vibrational pedigree of these carbon dioxide molecules, they plan to use these results to understand better other reactions between carbon dioxide and a variety of minerals.

UTS facility spearheads research in nanoscale materials physics A world-first facility giving scientists unprecedented control over the creation and testing of materials at the microscopic level has been commissioned at UTS. The UTS Faculty of Science has signed a $2 million collaborative research contract with American-based nanotech equipment manufacturer FEI Company that will support a new energy-efficient materials research strength at UTS. FEI is a world leader in the design, manufacture and distribution of focused electron and ion beam systems for nanoscale research. As part of the partnership, FEI has donated a novel, research-grade material fabrication and characterisation facility to UTS and is sponsoring Professor Milos Toth as a professorial chair in materials physics to spearhead the research and Gold flakes on tantalum surface development collaboration over a five-year period. [Image courtesy FEI Image Gallery] The cutting-edge laboratory is the first of its kind applied to research in the field of nanoscale materials physics using electron beams in reactive gaseous environments. Professor Toth, a former FEI research scientist, said the capabilities of the facility were “revolutionary” and UTS researchers would be the first to benefit. “This technology allows complex and dynamic material modification processes to be analysed in real time, creating a completely new approach to materials physics,” Professor Toth said. A highly advanced scanning electron microscope (SEM) enables processes such as the self-assembly of nanostructured materials to be performed in situ and to be studied using ultrahigh-resolution electron imaging and a unique combination of correlative chemical, elemental and optoelectronic analysis techniques. “This joint research venture is a great opportunity for FEI and UTS to further develop the technology and apply it to help make energyefficient materials a reality,” said Dr Michael Lysaght, FEI Company’s Director of Research and Technology. The facility has been installed in a special laboratory built and housed as part of the UTS Microstructural Analysis Unit (MAU). MAU Director Professor Matthew Phillips said, “The research findings will not only enable real-time dynamic studies of functional materials for sustainable energy applications but will also attract industry, prestigious research grants and facilitate a strong, long-term relationship between PhD student Aiden Martin and Professional Officer Geoff UTS and FEI to further develop research in energy McCredie at work in the PhD student Aiden Martin and Professional Officer Geoff McCredie at work in the new facility. efficiency and its applications.
