PFAS Testing and Regulatory Support

Our scientists apply a range of PFAS analysis methods to identity and determine levels of PFAS in samples. Targeted PFAS analysis offers superior sensitivity and chemical specificity, enabling the precise quantification of the analytes at trace levels. However, this approach is inherently constrained by its scope, as it fails to account for unidentified and polymeric fluorinated compounds. To partially mitigate this limitation, the Total Oxidizable Precursor (TOP) assay is frequently integrated into analytical workflows. By utilizing an oxidation process, the TOP assay converts polyfluorinated precursors into measurable perfluorinated carboxylic acids (PFCAs), thereby providing a more representative estimate of the total PFAS environmental load in a sample.

Non-targeted PFAS Analysis:
This addresses the inherent limitations of (non-)targeted analyses, which fail to detect polymeric PFAS species.
