In this article, the sensitivity of two-dimensional gas chromatography coupled to two different detectors — a time-offl ight mass spectrometer (GCXGC–TOF-MS) and a fl ame ionization detector (GC?GC–FID) — was compared to the sensitivity of conventional one-dimensional gas chromatography (GC–TOF-MS and GC–FID) by determining method detection limits (MDLs) for a series of different compounds with different polarities.

An interview with Hans-Gerd Janssen of Unilever Research and Development Vlaardingen and the University of Amsterdam. Janssen is involved with method development for gas chromatography, liquid chromatography, and mass spectrometry; the development of instrumentation for multidimensional chromatography for food analysis and biomacromolecular characterization; and problem solving and efficient routine analysis of foods (particularly oils and fats). This interview discusses the challenges encountered in the analysis of fats and oils, how multidimensional chromatography can be applied to the analysis, 2D LC for food-related compound analysis, the analysis of natural antioxidants in edible oils, and future steps in his research.

Special Issues
Gas chromatography with electron ionization and mass spectrometry (GC–EI-MS) detection is a workhorse among analytical techniques in metabolomics. A major challenge in the utilization of GC–EI-MS in metabolomics is the identification of unknowns.
