Per-and polyfluoroalkyl substances (PFAS) have been used worldwide in industry since the 1940s. PFAS are man-made chemicals, made of a carbon chain of variable length with very stable carbon-fluorine bonds. Their unique water-, grease-, and stain-resistant properties make them ideal for many products, such as food packaging, nonstick cookware, water repellent and stain-resistant fabrics, cosmetics, and firefighting foams. They are also critical in the manufacture of many products important for modern life, including medical technologies, semiconductors, batteries, phones, automobiles and airplanes.
To obtain reliable and accurate analyses of PFAS, it is important to use ultrapure water free of detectable levels of PFAS.
In this application note, ultrapure water from a Milli-Q® water purification system was tested for PFAS according to the draft EPA 1633 method. None of the 40 PFAS compounds tested were detected in the ultrapure water produced by a Milli-Q® IQ 7000 system fitted with a LC-Pak® polisher at the point-of-dispense, making it suitable for the most sensitive PFAS analyses by LC-MS/MS.
