The placing on the market and use of PFOS, PFOA and PFHxS, for example, is regulated in the POP Regulation (Regulation (EU) 2019/1021), while C9-C14 PFCAs are subject to the provisions of the REACH Regulation (Regulation (EC) No 1907/2006). In addition, many other PFAS have been added to the SVHC canidate list. This proficiency test offers you the opportunity to check your analyses of a large number of PFAS. You will receive 3 materials as part of this PT: Material 1 shall be extracted by using a solvent of your choice, e.g. methanol and be analyzed for PFAS. Material 2 shall be extracted by using alkaline hydrolysis based on EN 17681-1 and be analyzed for PFAS. Material 3 shall be used for the determination of total fluorine.
