Analysis of PFAS in soil, sediment, sludge and waste by HPLC and mass spectrometry cen:proj:78047

Scope

This document specifies a method for quantitative determination of various perfluorinated hydrocarbons by means of High Performance Liquid Chromatography (HPLC) and mass spectrometry in soil, sludge, sediment and waste (see Table 1)
This guideline must provide an adequate frame of reference for accreditation of this type of research. For many substances to which this document applies a limit of quantification (LOQ) of 0.1 µg/kgdm can be achieved.
The method can be applied to the analysis of additional PFAS not specified in the scope, if validity is proven by proper in-house validation protocols.

For each target compound both, eventually occurring branched isomers and the respective non-branched isomer, are quantified together.
In this method the total PFAS (total amount of linear and branched PFAS) is quantified using the response factor of the linear PFAS in the calibration standard and the total area of the linear and branched PFAS.
It can be noted that a validation test will be organised between at least 13 laboratories from 4 countries to establish this standard.
