Gas chromatography sample injector and apparatus using same |
摘要 |
The present invention relates to an improved sample injector for use in gas chromatography. The invention also includes a method of injecting a sample onto a chromatographic column, and a method of analyzing a sample using column chromatography and/or mass spectrometry. The improved sample injector features an arrangement to allow a pyrolytic probe to be more easily inserted into the vaporization cavity while permitting the sample to be volatilized in such a way that the sample is more efficiently introduced onto the column. Another feature of the invention is the use of means to reduce the volume of the pyrolysis/vaporization cavity so as to provide efficient throughput of pure sample. Also part of the present invention is a gas chromatograph and gas chromatograph-mass spectrometer which uses the sample injector of the present invention. The present invention includes methods of sample injection and sample analysis using the aforementioned apparatus of the present invention.
