The release of CIL® new 13C-labeled potassium trifluoromethanesulfonate (TFMS) analytical reference standard strengthen to its line of ultrashort-chain (USC) PFAS, which are primarily formed by industrial manufacturing, degradation of longer chain PFAS and other industrial compounds containing C-F bonds, photo-oxidation of hydrochlorofluorocarbon (HCFC) refrigerants and other atmospheric fluorocarbons, and as by-products of electrochemical fluorination and production of aqueous film-forming foams (AFFF). With the addition of 13C-TFMS, CIL® now provides an extensive set of native and labeled standards to more fully support USC PFAS analytical methods, including the new ASTM 8628-25. Learn more at Link
