Water quality — Determination of Chlorophenols in water using sorptive extraction with thermal desorption by gas chromatography-mass spectrometry

Scope

This document specifies the method of gas chromatographic determination of 5 chlorophenols (2-chlorophenol; 2,4-dichlorophenol; 2,4,6-trichlorophenol; 2,3,4,6-tetrachlorophenol; pentachlorophenol) in water samples.
NOTE 1 Other chlorophenols that is not specified in scope, it can be applied after confirming the validate.

This document describes a liquid/solid extraction method using immersive solid phase extraction samplers. After sampling, retained organic compounds are released by thermal desorption (TD) and automatically transferred to a gas chromatography-mass spectrometry (GC-MS) system for analysis.

This method is applicable to determination of chlorophenols in surface water, ground water and drinking water
