Article Number: 2011143
Description: Many per- and polyfluorinated substances (PFAS) are subject to various restrictions in the European Union. 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.
