Abstract: A number of samples from the same cigarette paper were pyrolyzed at different temperatures and analyzed by Pyrolysis Chromatography/Mass Sepectrometry(Py-GC/MS). The correlation coefficient of their fingerprint chromatograms was calculated with "intellectual fingerprint chromatogram identification system" software (version 1.0). The results indicated that the correlation coefficients of 4 repeat experiments at 600℃ were over 0.9600, while those at 400℃ and 500℃ were only higher than 0.9000. The correlation coefficient of Py-GC/MS fingerprint of cigarette paper samples at 600℃ could be used as an index in paper quality inspection.
