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 spectrometric techniques and other relevant factors. Note: This International Standard is also applicable for other environmental samples.
