GAS SAMPLING BAGS Non-contaminating, chemically inert, EPA recommended Gas sampling bags offer a convenient, reliable, economical way of collecting airborne chemical hazards. They are chemically inert, leak tested, mechanically strong, reusable, and noncontaminating. They are available in Tedlar®, Multi-Layer Foil, Charcoal Tedlar®, ALTEF, FEP, PFA, TFM and other materials, with a variety of standard and custom fittings as well as optional metal eyelets for easy holding and storage. Common applications       

Assessing exposure from spills and leaks Biogas and landfill sampling Calibrating Gas Standards Gas Blending Grab Sampling Magnetic Imaging Groundwater Testing

    

Measuring Peak Concentrations Indoor Air Sampling Vent Sampling Soil Gas Sampling Hazardous Waste Site Sampling

Tedlar® Bags Tedlar® film has very low gas permeation levels for most compounds, and high tensile strength. Bags resist puncture in the field. 2 mil Tedlar® film is an economical alternative to FEP bags. Tedlar® is much less permeable than FEP and is unaffected by the chemical components of gases generally sampled, like carbon monoxide, sulfur dioxide, hydrogen sulfide, radon and mercaptans. Continuous use temperature from –98° to 400°F (temperature limit depends on fittings used). Required for many EPA testing methods. ALTEF Bags ALTEF is a proprietary fluoropolymer film developed esspecially for the Gas Sampling market. ALTEF does not exhibit background levels of DMAC or phenol. ALTEF is not recommended for ketones or esters in high concentrations (>30%) and is not suitable for storing H2S. Maximum operating temperature: 260°F Multi-Layer Foil Bags Our Multi-Layer Foil bags are the best choice for collecting and storing H2S. Ideal for sampling and storing for low molecular weight compounds such as Methane, CO, CO2, Hydrogen, and inert gases which are not stable in Tedlar®, ALTEF, or FEP. Water and vapor proof, these opaque, flexible bags protect light sensitive compounds. They provide up to 5 day sample stability for many VOCs, with minimal adsorption. Custom sizes available. Maximum operating temperature: 190°F

FEP is one of the most chemically inert materials for making gas sampling bags. It works well in extreme temperatures ranging from –400° to 400°F; allowing it to be used in most stack sampling conditions. 5 mil FEP film is completely resistant to the most severe corrosives. Much more permeable than Multi-Layer or Tedlar®. FEP bags can be specified for applications involving corrosive gases.

GAS SAMPLING BAGS Non-contaminating, chemically inert, EPA recommended Re-using bags

Hints

The EPA does not recommend reusing sample bags for ambient air sampling, due to the possibility of adsorption of previously sampled chemicals onto the inside bag surface. In some cases, bags can be reused, with the following guidelines:



Before use, thoroughly flush bags with ultra-pure nitrogen or zero air



During sampling, Fluoropolymer tubing and Fluoropolymer faced septums must be used in order to prevent sample loss.

 Immediately after use, clean bags by flushing and heating, then store with all air evacuated from the bag.



Bags should not be filled to more than 80% of their maximum volume.



Charcoal (Black) Tedlar® bags should be used when sampling light sensitive compounds



Do not store compounds in Tedlar® bags long term due to the possibility that chemicals may adsorb onto the bag surface.



Bags should not be used to collect reactive or unstable compounds.



When shipping bags, do not air-ship unless the bags are stored in a pressurized area..

 Long-term storage of air-contaminant mixtures in bags can cause subsequent samples to be contaminated by off-gassing of previous samples adsorbed into the film.  Tedlar® bags can be used for higher MW alcohols without contaminating subsequent samples if cleaned and flushed properly.  Properly cleaned bags can be reused for sampling ethers without interfering with subsequent analysis.

 Tedlar® bags used for sampling styrene or ethyl benzene cannot be reused. Cleaning and flushing will not completely remove these chemicals.
