Gas Chromatography/Mass Spectrometry and Gas Chromatography/Tandem Mass Spectrometry of some s-Triazine Pesticides
Yoo Joong Kim, Myung Soo Kim*
Some s-triazine herbicides, namely simazine, atrazine, and propazine present as trace components in a complex mixture were analyzed by GC/MS and GC/MS/MS methods. Even though monitoring the molecular ions was the best in terms of sensitivity, adequate analysis could not be done when interfering species were present. When doubly charged ions which appeared at characteristic m/z values were monitored, chromatograms were rather free from interference. More importantly, selected reaction monitoring was found to provide a selective means of detection with general applicability.
