Water quality — Multi-compound class methods — Part 1: Criteria for the identification of target compounds by gas and liquid chromatography and mass spectrometry

Qualité de l'eau — Méthodes d'analyse de composés multi-classes — Partie 1: Critères pour l'identification de composés cibles par chromatographie en phase gazeuse ou liquide et spectrométrie de masse

Abstract / scope

This document specifies the criteria for mass spectrometric identification of target compounds in water samples and is applicable to environmental samples in general. This document is intended to be used in conjunction with standards developed for the determination of specific compounds. If a standard method for analysing specific compounds includes criteria for identification, those criteria are followed.
