Inlet system for direct gas chromatographic and combined gas chromatographic/mass spectrometric analysis of food volatiles |
摘要 |
An apparatus for analyzing volatile components from raw or processed food products using either direct gas chromatography or combined direct gas chromatography and mass spectrometry is disclosed. An inlet assembly containing a sample is appropriately affixed to a means of supplying helium carrier gas. Volatiles are driven off the sample and fed to a condenser assembly where the moisture is removed. The resultant moisture free volatiles are fed to a gas chromatograph or combined direct gas chromatograph and mass spectrograph for analysis.
