Gas Chromatograph-Mass Spectrometer

LAURIE DUNCAN

The gas chromatograph-mass spectrometer (GC/MS) is an instrument used to analyze the molecular and ionic composition of chemical compounds. GC/MS technology combines two widely used laboratory techniques: gas chromatography (GC), which separates and identifies compounds in complex mixtures, and mass spectrometry (MS), which determines the molecular weight and ionic components of individual compounds. The combination of these two powerful tools into a single instrument the chemical separates produced by the gas chromatograph become the input for the mass spectrometer allows for quick, precise analyses of ...
