Gas chromatography (GC) separates compounds that may be vaporized without decomposition when heated. To do so, analytes, in contact with the gaseous mobile phase, are brought to high temperatures. The same goes for the stationary phase caught in the column. GC can be paired with many types of detection, especially mass spectrometry, which often helps in positive identification of analytes. This versatile and very sensitive technique is known for its quick optimization of analytical conditions, and thanks to current advances, such as high‐speed or multidimensional gas chromatography, it is a very attractive and essential resource when studying volatile compounds.
