A sample introduction device for introducing a vaporized sample to the ion source of a mass spectrometer of a combined gas chromatography-mass spectrographic (GC/MS) apparatus. The sample introduction device replaces the jet separator of the GC/MS apparatus. The sample introduction device includes a sample holding tube which is releasably attachable to the isolation valve between the gas chromatography column and the mass spectrometer of the GC/MS apparatus. The sample introduction device includes means for connecting the sample holding tube to a vacuum source by means of a valve so that the sample holding tube can be evacuated prior to connecting the sample holding tube through the isolation valve to the ion source of the mass spectrometer.
