Abstract

An integral gas chromatograph / mass spectrometer system is assembled by attaching a gas chromatograph assembly on one side and a mass spectrometer assembly on the other side of a master flange. The gas chromatograph assembly is accurately positioned on a holder board integrally connected to the master flange. The mass spectrometry assembly is accurately positioned on a base plate that is integrally connected to the master flange.
