On-line heart-cut LC–GC and, more recently, comprehensive LC–GC (LC?GC) are very powerful analytical techniques because of the combination of the selectivity features of LC with the high efficiency of GC. This article presents an overview of the most recently used interfacing systems, as well as applications in the food analysis.

Gas chromatography?mass spectrometry (GC?MS) combines a gas chromatographic front-end separation with a mass spectrometer. For the most part, the gas chromatographs and mass spectrometers used are modular in design and relatively easily separable. GC?MS is the most widespread tandem technique in the analytical instrumentation industry, which are employed across many different industries, particularly for environmental, chemical and toxicological applications.
