| Abstract: | Pyrolysis gas chromatography-mass spectrometry was used to analyse the pyrolysis products of some domestic brand cigarettes. And some explorations have been done on the analysis of the aroma constituents in cigarette by the application of pyrolysis method.The results obtained indicated that the components were different from the different samples, and these showed the information of interrelationship to the different tastes of the samples. The method has a good repeatability (relative standard devariation bellow 10%). The results could supply much information in developing cigarette, selecting additives,and also for studing or addressing several areas related to pyrolysis kinetics and mechanisms. |
