Determination of 2-Methylisoborneol, Geosmin and 2,4,6-Trichloroanisole in Drinking Water by Dynamic Headspace Coupled to Selectable 1D/2D GC/MS with Simultaneous Olfactory Detection

Abstract

A method for the determination of trace amounts of off-flavor compounds such as 2-methyl isoborneol (MIB), geosmin and 2,4,6-trichloroanisole (TCA) in drinking water is described based on dynamic headspace coupled to selectable one dimensional or two-dimensional gas chromatography – mass spectrometry with simultaneous olfactory detection(DHS-1D/2D-GC-O/MS).
