New Products Spectrometer Ocean Optics has added triggering functions to its Maya2000 Pro back-thinned CCD miniature spectrometer to provide accurate timing and synchronization between the spectrometer and other devices. Three lowjitter trigger and normal operating modes are now possible. Applications include pulsing a light source to occur when acquiring a spectra and synchronizing spectral acquisition to coordinate with samples moving through a process stream or sensors reaching a certain temperature level. In addition to triggering, Ocean Optics has enhanced Maya2000 Pro performance with support for RS-232 communications and improved optoelectronics that increase dynamic range (to 15000:1), lower trigger jitter (to 100 ns) and decrease dark noise (to 6 RMS counts). The Maya2000 Pro has a 30-pin connector and 10 user-programmable digital I/Os. Its onboard programmable high-speed FPGA controller enables triggering and provides other performance advantages. Available operating modes are Normal (spectrometer continuously acquires spectra) and the three trigger modes: external hardware level trigger, external synchronous trigger and external hardware edge trigger. The Maya2000 Series spectrometers are ideal for low light-level applications such as fluorescence, DNA sequencing and measurement of certain biological samples. The spectrometer can be used in the VUV (to ~150 nm) with the addition of a nitrogen purge box to help lessen the absorption of water and oxygen in the VUV.

Dispensing Auxiliary Modules METTLER TOLEDO introduces new Quantos® powder and liquid dispensing auxiliary modules that can be added to any 0.1mg or 0.01mg XP Excellence Series analytical balance. The addition of automated powder and liquid dispensing functionality to the balance increases laboratory efficiency, improves results, and eliminates errors in weighing, sample preparation, dilution and transcription. Additionally, the Q2 powder dispensing module lets users take advantage of Quantos dispensing head technology which automatically dispenses the compound to a target weight and replaces the tedious activity of weighing out powders by hand with a spatula. By also serving to store the compound, the dispensing head improves the containment of dangerous compounds during weighing, and provides new ways for laboratories to maximize compound yields and to improve workflows. The Quantos Q2 and QL2 kits are available to anyone with a previously installed or newly purchased XP Series analytical balance having 0.1mg or 0.01mg readability. Complete retrofit services, including equipment qualification is also available from METTLER TOLEDO.

Pump Edwards’ new nXDS pump is an environmentally-friendly oil-free vacuum pump that has no lubricants in the vacuum. This eliminates the need for regular oil changes and users can benefit from low maintenance. It is fully serviceable in the field, which results in low downtime. It has reduced power consumption with minimum environmental impact and low acoustic noise levels, making it an ideal ‘fit and forget’ pump for the laboratory. The pump also features green modes, enabling users to reduce their carbon footprints and save energy costs.

The Syrris Asia 330 is an integrated flow chemistry system that expands on the capabilities offered by other Asia systems by including the FLLEX module for flow aqueous work-up and the Asia Sampler and Dilutor, which allows integration of analytical devices such as liquid chromatography mass spectrometers (LCMS). Factors such as reaction time, temperature and reagent ratio can be varied and each reaction is collected and analysed automatically. Furthermore, the automatic control of syringe pumps, injection reagents, synthesis and waste diversion enable hundreds of solutions or phase experiments to occur. Asia Master PC software allows 1,000’s of system configurations, single or multi step reactions, graphical display of data and full data logging. The system also incorporates maximum chemical resistance with wide temperature (-15 to 250 °C) and pressure (0-20 bar) ranges.
