ABSTRACT
Standard Reference Materials (SRMs) are homogeneous, well-characterized materials used to validate analytical measurements and improve the quality of analytical data (www.nist.gov/srm). The National Institute of Standards and Technology (NIST) has a wide range of SRMs with values assigned for legacy organic pollutants. SRMs can serve as target, matrix matched materials for method development and quality assurance and quality control (QA/QC) of chemical measurements. As a unique class of organic contaminants, per and polyfluoroalkyl substances (PFAS) present measurement challenges to the environmental analytical community and affect the accuracy and precision of quantitative measurements. Currently, NIST has eleven different reference materials with values of PFAS measured; however, there are relevant gaps in the NIST library of reference materials. We will discuss the existing reference materials, along with the past and current efforts at NIST to produce new reference materials for PFAS.
