FlexFoil PLUS Sample Bags
Specially Cleaned for Low ppm to High ppb-Level VOCs
FlexFoil is available as Standard FlexFoil

  • FlexFoil is now available in Standard and PLUS
    • Standard FlexFoil offers economy for sulfur compounds and low molecular weight gases
    • FlexFoil PLUS is specially cleaned for low-level (ppb) VOCs in addition to sulfur compounds and low molecular weight gases

  • Low backgrounds
    • Specially cleaned FlexFoil PLUS provides VOC detection and good storage stability

  • Good stability for low molecular weight compounds such as CO, CO2, methane, hydrogen, and SF6

  • Good 48-hour stability for hydrogen sulfide, hydrogen, carbonyl sulfide, and methyl and ethyl mercaptan

  • Strong, flexible, evenly sealed 4-ply (5-mil) material

  • Light and moisture-proof
    • Excellent for light-sensitive compounds

  • Choice of all-in-one polypropylene or stainless steel hose/valve and septum fittings

  • Stocked in a variety of sizes; custom bags available

  • Breath-gas analysis bags for end-exhaled air determined BEIs

FlexFoil PLUS Breath-gas Analysis Bags
SKC Breath-gas Analysis Bags are ideal for collecting samples of human breath to be analyzed for volatile organic compounds (VOCs) or volatile sulfur compounds (VSCs), possible biomarkers for some diseases. Each sample bag contains a specially designed stainless steel fitting with disposable plastic mouthpiece that facilitates collecting human breath samples and removing the sample for gas chromatography (GC) analysis. SKC Breath-gas Analysis Bags are offered in FlexFoil PLUS (below), Tedlar , and SamplePro FlexFilm . See the Bag Stability Report (PDF) for information on bag material stability.
