Still hot: gas chromatography has been around for some time but has constantly been improved. Today’s instruments are more rapid and sensitive and are able to work with a variety of detectors. Coupled with mass spectrometers (GC-MS), gas chromatographs can not only separate the substances in mixtures but also easily identify and quantify them. For several industry applications combination systems are available that, for example, also encompass TG and LC.
