Tedlar®  Film Use in Gas Sampling Bags

Posted by Mack Hendrick on Aug 11, 2016 2:35:14 PM

Tedlar® Film Offers Gas Permeation Resistance for Gas Sample Bags

DuPont™ Tedlar® PVF film is a biaxially oriented and highly functional film that provides long-lasting finish, making it a much sought after high-performance material.

Apart from being used in a wide variety of industrial market surfaces, its chemical inertness and resistance to gas permeation makes Tedlar® a top choice for scientific pursuits that require gas sample bags. Sample integrity is assured as Tedlar® release films offer gas permeation resistance into and out of the sample bags.

Gas sampling bags are whole air sampling devices useful for monitoring part-per-million (ppm) levels of volatile organic compounds (VOCs) and permanent gases. Used for industrial hygiene, landfill/biogas, ambient air, indoor air, and stationary source testing, sampling bags are a cost-effective alternative to canisters and solvent desorption tubes.

Because Tedlar® is chemically inert, it will not react with or alter the composition of the wide range of collected chemicals in your sample. Gas sampling bags made of Tedlar® PVF film are recommended in many US EPA methods including toxicity characteristic leaching procedure (TCLP) and methods TO-3 (VOCs), TO-12 (NMOC), TO-14A (VOCs), TO-15 (VOCs), ASTM D-5504 (reduced sulfur compounds) and a variety of atmospheric gas methods.
