Abstract
The National Institute of Standards and Technology (NIST) Reference Materials (RMs) 8690 Per- and Polyfluoroalkyl Substances (PFAS) in Aqueous Film-Forming Foams (AFFF) Formulation I, RM 8691 Per- and Polyfluoroalkyl Substances (PFAS) in Aqueous Film-Forming Foams (AFFF) Formulation II, RM 8692 Per- and Polyfluoroalkyl Substances (PFAS) in Aqueous Film-Forming Foams (AFFF) Formulation III, and RM 8693 Per- and Polyfluoroalkyl Substances (PFAS) in Aqueous Film-Forming Foams (AFFF) Formulation IV deliver non-certified values of the identity and quantity of per- and polyfluoroalkyl substances (PFAS) in four formulations prepared from commercial aqueous film-forming foam (AFFF) products. These RMs are intended for use as quality control materials for PFAS measurements; they are not meant for use in establishing the metrological traceability of measurement results to the International System of Units (SI). Each unit of these RMs consists of one ampoule containing approximately 1.2 mL of an AFFF solution diluted 10:1 (vol:vol) in methanol and modified by addition of PFAS analytical standards. This publication documents the production, analytical methods, and computations involved in characterizing these products.
