Gas chromatography Mass Spectrometry is a latest range of analytical instruments designed to offer superior performance and accuracy. Chromatography alone cannot be used to conduct qualitative analysis as its column features highly efficient separation capability depending on the material's retention time and the material's nature is then determined through contrast with the samples. Mass spectrometry is capable to directly determine the mass ratio to the charge ratio (m/z) which is highly accurate and fast.

Mass spectrometry is used as a universal detector with a combination of chromatography and mass spectrometry. Several detectors of chromatography are available such as TCD, FID, ECD, FPD and NPD, etc with each detector having limited scope of application which is inconvenient. The chromatography and mass spectrometry instrument combines the technologies of chromatography, mass spectrometry and computer. The device is helpful in cases where gas chromatography is used for detection especially where qualitative analysis is to be conducted on the unknown samples.
