Gas chromatography mass spectrometry (GC-MS)

Gas Chromatography combined with Mass Spectrometry is a powerful technique to identify or quantify (semi) volatile compounds. The sample is injected into the GC-MS and separated based on boiling point and affinity with the column. The separated components are subsequently ionized, and the resulting mass spectra can be used to identify the individual components. Identification is aided by comparison to MS spectra in the NIST database.
