[Quality control of tobacco flavour by gas chromatography]

In this work, gas chromatography with hydrogen flame detector(FID) and catalytic combustion detector(CCD) was applied to fast analysis of tobacco flavour. The results are satisfactory. Whether the FID or CCD is used, it has its respective characters. Though the sensitivity of GC/CCD is a little bit lower than that of GC/FID, the operation of the former is easier, more convenient and safer. The GC/CCD only uses air as the carrier gas. The column of GC/CCD was SE-54 megabore capillary column(50 m x 0.53 mm i.d.). In this method, all of the interesting flavour compounds are responsed. We have presented some relative correction factors (f1) about flavour compounds in this paper. The satisfactory results show that this new method has certain practical value as an approach of quality control.
