PFAS Compounds

PFAS reference standards — per- and polyfluoroalkyl substances — for analysis of drinking water, wastewater, soil and food under US EPA 533, 537.1 and 1633 and ISO 21675.

The range covers PFOA, PFOS, PFHxS, PFNA, short-chain homologues, precursors and carbon-13 labelled standards for use as internal standards. Because PFAS are quantified at ng/L levels, isotope-labelled standards are practically essential to correct for matrix effects. See also environmental reference standards.
