Gas chromatography is a powerful tool for separation of volatile small molecule analytes. Samples are volatilized in the injector and then separate based on hydrophobicity and boiling point in the GC column, followed by mass determination in the MS. Results can be searched against the NIST MS libraries to identify compounds. Coupled to triple quadrupole mass spectrometry this enables quantitation of e.g. metabolites. Robotic auto-sampler can perform normal liquid-phase sample injection as well as headspace and SPME pretreatments.
