Sediment, Soil, sludge and waste - Analysis of PFAS by HPLC and mass spectrometry(ISO/DIS 25652:2025)

Апстракт

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).

For many substances to which this document applies a limit of quantification (LOQ) of 0.1 to 10 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 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 (Annex 1 gives more explanation)
