Gas Chromatograph –Mass Spectrometer

Principle:
The Gas Chromatography/Mass Spectrometry (GC/MS) instrument separates chemical mixtures (GC) and identifies the components at a molecular level (MS). During the GC, a mixture will be separated into individual substances when heated and carried through a column with an inert gas (e.g. Helium). The separated substances by the column opening are flowing into the MS, which identifies compounds by the mass of the analyte molecule and search in mass library (stored on the PC), which is provided with several thousand compounds.
