Gas Sampling Bags

Please See Alternative ALTEF and Multi-Layer Foil Gas Sampling Bags Comparison Charts.

Gas Sampling Bags are the first choice for collecting a variety of gaseous compounds. Gas Sampling Bags are referenced for many U.S. EPA Methods including 3,18 and 0040. Bags fabricated from film are inert to most gases, resist gas permeation and can be reused for most applications after proper cleaning. They are flexible and strong, and use of a rigid container ensures a longer life and convenience during transporting. Gas Sampling Bags are fabricated from transparent 2ml film or can be special ordered fabricated from opaque black for photosensitive compounds. Custom sizes available upon request. Sample bags come standard fitted with the Poly 2-in-1 Combination Valve and  Septum Fitting. Each standard bag has one fitting located near the top center or in the center of the bag. Custom placement available.

Color Code:
     Red - Not Suitable 
     Dark Green - Recommended
     Ligth Green - Suitable when used as recommended

     • ALTEF bags can be used to sample these sulfur compounds if sample is analyzed within 24 hours.

    ◊ Multip-Layer Foil bags can be used to sample most VOCs but are not recommended for collecting low ppm to  
        high ppb VOCs due to background levels from bag materials.

       ALTEF bags are recommended for most VOCs, if analyzed within 48 hours, and for many sulfer compounds, if
       analyzed within 24 hours.

       Multi-Layer Foil bags are recommended for Methane (CH4), Hydrogen Sulfide (H2S), Carbon Monoxide (CO), 
       and Carbon Dioxide (CO2), if analyzed within 48 hours.
