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.
