CIL is happy to announce the release of a new 13C-labeled potassium trifluoromethanesulfonate (TFMS) analytical reference standard to its line of ultrashort-chain PFAS offerings!
Ultrashort-chain (USC) PFAS are a class of C1 to C3 chain length compounds from the perfluorocarboxylic acid (PFCA), perfluoroalkyl sulfonate (PFAS), per- and polyfluoroether carboxylic acid (PFECA), and perfluorinated sulfonylimide (PFSI) groups.
USC PFAS 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).
Due to their shorter chain lengths, USC PFAS are very persistent, extremely soluble in water, and exhibit increased mobility in soil and water matrices, giving them the ability to travel faster and farther than longer chain PFAS. They have been detected at high levels in various water sources including rainwater, surface water, drinking water, and wastewater effluent, at hazardous waste sites, as well as in dust and indoor air.
Existing analytical methods for targeted compounds generally focus on analysis of PFAS with chain lengths of C4 or greater. With increased detection in air, water, and human exposure studies, and growing concern over potential health impacts, many laboratories are now offering analysis of USC PFAS. However, due to their small sizes and high polarity, USC PFAS can be very difficult to analyze along with their longer chain counterparts via traditional methods. CIL’s new and existing stable isotope-labeled and unlabeled USC PFAS reference standards provide a high degree of confidence in qualifying and quantifying these compounds.
With the addition of 13C-TFMS, CIL now provides an extensive set of native and labeled standards to more fully support ultrashort-chain PFAS analytical methods, including the new ASTM 8628-25. And keep looking for additional PFAS reference standards and multicomponent mixtures coming soon from CIL!
