Perfluorooctanoic acid (PFOA) and perfluorosulfonic acid (PFOS) are among the most widely studied PFAS, but while their production continues in other parts of the world, their manufacture is no longer permitted in the US, EU and other parts of the world. The import of certain PFAS-containing products into the US is regulated by EPA reviews and the Toxic Substances Control Act (TSCA), but many PFAS products remain unregulated in their use in commercial and domestic products.Because the full extent of PFAS risks to the environment and human health is still being investigated, it is important that these chemicals can be consistently detected with high accuracy. Reliable, trace-level PFAS data will help inform the regulation of further PFAS compounds used in industry. LC/MS is often used as a means of accurately detecting PFAS at the low levels typically found in the environment. For this purpose, Agilent not only provides solutions featuring ultrahigh performance liquid chromatography (UHPLC) and triple quadrupole mass spectrometry (MS) systems, but also entire turnkey workflows in the form of eMethods, comprising of sample preparation, extraction, quantification, and reporting protocols.
