Abstract
Conventionally, the mass spectrometer unit is placed beside the gas chromatograph unit when the gas chromatograph unit is coupled with a mass spectrometer unit, whereas the normal detector is placed on the top of the gas chromatograph unit when it is coupled with a normal detector. This requires different structure of the gas chromatograph unit. In the gas chromatograph/mass spectrometer (GC/MS) system of the present invention that uses a suitably modified and re-designed mass spectrometer, the mass spectrometer unit is mounted on the top of the casing of the gas chromatograph unit. Thus a common gas chromatograph unit can be used whether it is coupled with a normal detector or with a mass spectrometer unit. Another advantage of the GC/MS system of the present invention is that it occupies less table-top or floor space.
