摘要：

Electrospray mass spectrometry has aided the structural characterization of triazine herbicides standards. Possible fragmentation routes were first obtained by controlled collision-activated dissociation (CAD) initiated by cone voltage fragmentation. Low energy CAD MS-MS analyses of the protonated molecules [M+H](+) confirmed the characteristic fingerprint patterns obtained by cone voltage fragmentation for all investigated triazine herbicides and also permitted differentiation of isomeric triazines. MS-MS analyses of selected intermediate fragments provided additional structural data, and established the fragmentation routes of their [M+K](+) precursors. Electrospray MS has been proven to be a specific and very sensitive method for the detection and characterization of herbicides.
