The collision‐induced dissociation, (CID) mass spectra of 11 common s ‐triazine herbicides were investigated using gas chromatography/tandem mass spectrometry on an ion trap mass spectrometer with a temperature‐programmable injector. The precursor ions of the CID mass spectra studied included both the molecular ions and the major electron ionization (EI) fragment ions. Typical fragmentation processes were observed, including simple cleavages, cleavages with hydrogen transfer rearrangements and skeletal rearrangements, involving opening of the triazine ring. Based on these results, EI fragmentation pathways of the triazines studied were derived. The better understanding of the dissociation processes and pathways should improve target compound analysis of these herbicides in environmental samples. © 1997 John Wiley & Sons, Ltd.
