Soil quality. Guidelines for the identification of target compounds by gas chromatography and mass spectrometry1 Scope This International Standard gives criteria for gas chromatography and mass spectrometry (GC MS) identification of target compounds in soil samples. This International Standard is intended for use with standards developed for the determination of specific compounds. The identification criteria are based on the comparison of retention times followed by interpretation of the electron ionization mass spectra, or if necessary, additional mass
