FlexFoil® Sample Bags provide light and moisture protection for low molecular weight compounds such as hydrogen that are unstable when collected into standard sample bags for VOCs. Four strong layers prevent permeation in and out of the bags. The inert inside surface minimizes absorption and adsorption of compounds.

FlexFoil Sample Bag Applications*

  • Biogas and landfill gas (LFG) sampling
    • Sewage treatment plants and landfills
    • Emission control
    • Fruit warehouses and fermentation cellars
    • Farms
  • Pollution level monitoring in work areas
  • Site sampling and mobile surveys
  • Transferring calibration gas from lab to instrument
  • Preparing calibration mixtures
  • Assessing exposure from leaks and spills
  • Indoor air studies (CO, CO2)
  • Carbon dioxide in workplace atmospheres (OSHA ID-172)
  • Carbon dioxide (NIOSH 6603)
  • Carbon monoxide (OSHA ID-210 )
* FlexFoil sample bags are not suitable for collecting VOCs due to the constituents of the FlexFoil material
Method specifies 5-layer foil bags. SKC 4-ply FlexFoil bags hold 100 ppm CO for 5 days without loss. See Analysis of FlexFoil Bags for Carbon Monoxide, Carbon Dioxide, and Hydrogen (PDF).
