How does Restek determine the purity of PFAS standards?

28 Aug 2025

Our PFAS standards are manufactured under our ISO-accredited certified reference material (CRM) processes. Purity and/or chemical identity are determined by one or more of the following techniques: GC/FID, HPLC, GC/μECD, GC/MS, LC/MS, RI, and/or melting point.

PFAS material was tested for targeted trace PFAS analysis (<1%)  by LC MS/MS and isomeric identification is confirmed by 19FNMR.
