Gas Chomatograph Mass Spectrometer: Varian saturn III

Gas Chomatograph Mass Spectrometer: Varian saturn III

Principle

GC/MS is a combination of a chromatographic and spectral method. Chromatograph produces ‘pure’ fraction from your sample while Massspectrometer yields qualitative information about a ‘pure’ component.

Theory

The mass spectrometer is a universal detector for gas chromatographs since any compound that can pass through a gas chromatograph is convertedinto ions in mass spectrometer. At the same time, the highly specific nature of mass spectrummakes the mass spectrometer a very specific gas chromatographic detector. Gas chromatography is an ideal separator, whereas mass spectrometry is excellent for identification. The aim of an interfacing arrangement is to operate both a gas chromatographand a mass spectrometer withoutdegrading the performance of either instrument.
