    • There is provided a method for sample introduction into a gas chromatograph for performing sample analysis, in which a sample is introduced into a removable sample container, the container is placed in a sample introduction device, the device with said container is inserted into a gas chromatograph injector, and the sample is then vaporized for effecting analysis thereof by the gas chromatograph. The non-volatile residues of the sample retained in the container after vaporization and are removed with the container prior to performing the next analysis. There is also provided a method for direct sample introduction into a mass spectrometer for performing sample analysis, in which a sample is loaded into a sample container, the container with the sample is introduced into the injector of a gas chromatograph connected to a mass spectrometer through a capillary column, the injector is heated to a temperature sufficient to vaporize the sample to produce a flow of compounds which are swept to the mass spectrometer by a carrier gas, and the container is removed from the injector prior to performing the next analysis. Devices for introducing samples into a gas chromatograph for analyzing said sample are also described and claimed.
    • 提供了将样品引入气相色谱仪进行样品分析的方法,其中将样品引入可移除的样品容器中,将容器放置在样品引入装置中,将具有所述容器的装置插入气相色谱仪 注射器,然后将样品蒸发以通过气相色谱仪进行分析。 蒸发后样品的非挥发性残留物保留在容器中,并在进行下一次分析之前用容器除去。 还提供了将样品直接引入质谱仪进行样品分析的方法,其中将样品装载到样品容器中,将具有样品的容器引入连接到质谱仪的气相色谱仪的注射器中,通过 毛细管柱,将注射器加热到足以蒸发样品的温度,以产生通过载气扫过质谱流的化合物流,并且在进行下一次分析之前从容器中取出该容器。 还将对用于将样品引入用于分析所述样品的气相色谱仪的装置进行描述和要求保护。
