This poster presents an evaluation of Agilent PFAS Bond Elut WAX and Agilent Carbon S for the extraction and matrix cleanup of per- and polyfluoroalkyl substances (PFAS) in solid matrices following the protocols specified in United States Environmental Protection Agency (US EPA) draft method 1633 (December 2022). Results obtained in this study were comparable to results reported in the draft method for the single laboratory validation study. The overall average recovery accuracy of native PFAS and extracted internal standards from solid matrix was determined to be 98 ±2% in this study compared to 94 ±4% in the draft method (95% confidence level, 64 measurements). The overall precision was also comparable. For both data sets, the measurement precisions were well below 20%. For the draft method, the overall average RSD was 3.9 ±0.6%, and for this study, the overall average RSD was 3.8 ±0.6% (95% confidence level, 64 measurements).
