Fast gas chromatograph method and device for analyzing a sample

摘要

In a fast gas chromatograph (GC) method and device for obtaining fast gas chromatography analysis, a capillary gas chromatography column is inserted into a resistively heated metal tube located mostly outside a standard gas chromatograph oven, which may serve as a heated transfer line to a flexible column that enters the resistively heated metal tube from its injector and exits into its detector. The fast GC device enables less than one minute full range temperature programming and cooling back analysis cycle time. The fast GC according to one embodiment is combined with mass spectrometry with supersonic molecular beams for the provision of fast analysis cycle time together with highly informative mass spectral information for improved sample analysis and identification.
