This article provides a short overview of the theory and practice of the rapidly developing field of two‑dimensional gas chromatography (GC×GC). Included in the discussion are a summary of the detectors used, an assessment of the options available for modulating the first-column eluate, and some recent developments in methodologies for interpreting the results.

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.
