Abstract:In order to test the quality and characteristics of faint-scent cigarettes by the technology of GC—MS and electronic nose fingerprint, the method of SDE combined with GC—MS and electronic nose were used to construct their standard and radar fingerprints. Samples of non faint-scent cigarettes were selected to study the standard fingerprint. Results of similarity calculation showed that six batches of faint-scent cigarettes had a much higher similarity with the standard fingerprint, and the extent similarity was more than 85%, while the other six batches of non faint-scent ones had a lower similarity. This indicated that the faint-scent and non faint-scent cigarettes marked difference in quality and characteristics. Moreover, compared with electronic nose radar fingerprint, six batches of non faint-scent cigarettes were located the outside acceptable area of SQC, and this was accordant with the result of similarity calculation. In conclusion, SDE/GC—MS and electronic nose fingerprint is feasible and can be used for the quality and characteristics control of faint-scent cigarettes.
