Ordering Information - Vials
According the United States EPA website, "Per- and polyfluoroalkyl substances (PFAS) are a group of man-made chemicals that includes PFOA, PFOS, GenX, and many other chemicals. PFAS have been manufactured and used in a variety of industries around the globe, including in the United States since the 1940s. PFOA and PFOS have been the most extensively produced and studied of these chemicals. Both chemicals are very persistent in the environment and in the human body – meaning they don’t break down and they can accumulate over time. There is evidence that exposure to PFAS can lead to adverse human health effects".
It may important to add that there are official EPA, PFAS Testing Methods for Drinking Water (USEPA 537 or 533), Groundwater,Wastewater and Solids and Soil (USEPA 8327).
PFAS are used in the manufacturing of PTFE; to properly test for PFAS by chromatography, LCMS/MS or GCMS is often used and the Autosampler Vials and Caps should not contain any PFAS, or PTFE. Our AQ™ Brand Caps designed for PFAS Testing and Storage are manufactured with our purest Silicone Rubber and pure, virgin, medical grade polypropylene and without any PTFE. Our single-use Cap is the purest cap available today.
