Steen, R.J.C.A.; Leonards, P.E.G.; Brinkman, U.A.Th.; Cofino, W.P. (1997). Ultra-trace-level determination of the antifouling agent Irgarol 1051 by gas chromatography with tandem mass spectrometric detection. J. Chromatogr. 766(1-2): 153-158. http://dx.doi.org/10.1016/S0021-9673(96)01039-4
The contamination level of the s-triazine herbicide Irgarol 1051, which is used as the active ingredient in antifouling paints, was studied in the Western Scheldt estuary. The combined use of large-volume injection gas chromatography and ion trap (MS–MS) detection, enabled identification and quantification at the 0.1–1 ng/l level. By using tandem mass spectrometric detection (MS–MS), rather than conventional MS, a great gain in selectivity was achieved. The concentration levels found ranged between 1 and 10 ng/l.
