    • 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.
    • 用于将气化样品引入组合气相色谱 - 质谱(GC / MS)装置的质谱仪的离子源的样品引入装置。 样品引入装置代替GC / MS装置的喷射分离器。 样品引入装置包括样品保持管,其可释放地附接到GC / MS装置的气相色谱柱和质谱仪之间的隔离阀。 样品引入装置包括通过阀将样品保持管连接到真空源的装置,使得在将样品保持管通过隔离阀连接到质谱仪的离子源之前,样品保持管可以被抽真空。
