PFAS, or per- and polyfluoroalkyl substances, are a group of synthetic chemicals that have been used in a wide range of industrial and consumer applications since the 1940s. PFAS are valued for their unique properties such as water and grease repellency, non-stickiness, and heat resistance. They are commonly used in products such as Teflon cookware, firefighting foams, waterproof clothing, and food packaging. PFAS are "forever chemicals", chemicals that are very persistent in the environment and in the human body.
Why PFAS use polypropylene vials instead of glass vials?
Many top companies have finished the evaluation, Polypropylene vials are the best choice for doing PFAS analysis, as the adsorption effect is the lowest, and thus the signal strength of the analytes is the best.
When you are unable to use PTFE as a liner, Polyimide is the perfect replacement.
