Water quality. Multi-compound class methods - Criteria for the identification of target compounds by gas and liquid chromatography and mass spectrometryWhat is ISO 212531 GC MS and LC MS for target compounds in water about? ISO 212531 is the first part of the multi series on water quality multi compound class methods. ISO 212531 specifies the criteria for mass spectrometric identification of target compounds in water samples and applies to environmental samples in general. The use of gas chromatography (GC) and liquid chromatography (LC) in combination with mass spectrometric (MS) detection is common
