Abstract
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.
