ABSTRACT
Gas chromatography (GC) is only pertinent for the separation of volatile substances and so extremely involved derivatization procedures were developed to render intractable substances volatile and thus amenable to the new technique. A more rational approach is used by analysts and the appropriate analytical technique is chosen to suit the properties of the sample. GC can offer greater sensitivities than liquid chromatography and, if required, those high sensitivities can be far more specific. GC separations can be achieved in a few seconds on both packed and capillary columns if so desired, but the separation itself is not the critical step in most chromatographic analyses. The separation and analysis of the permanent gases is one of the more popular applications of GC. An interesting separation of the components likely to be present in a Fermentation Product was developed by DiCorcia et al. at the University of Rome.
