Recent developments in the miniaturization of gas chromatography–mass spectrometry (GC–MS) instrumentation are making the technique available for field-based investigations, offering a simple, onsite identification of drug substances. This article describes the identification of sixteen drugs compounds in less than 10 min using portable gas chromatograph-toroidal ion trap mass spectrometry combined with a coiled-wire-filament (CWF) sampling injector to provide an effective tool for the rapid analysis of illicit drug substances.
