Method for fast gas chromatography identification of quality of tobacco flavors for invitation for bids

The invention discloses a method for fast gas chromatography identification of quality of tobacco flavors for invitation for bids and belongs to the technical field of flavor quality control. The method comprises steps as follows: chromatograms of a standard sample and bidding samples on two chromatographic columns are acquired by using a HERACLES II type ultra-fast gas chromatography electronic nose system; linear conversion is performed on primary data vectors with a PCA (principal component analysis) method, and one of the bidding samples, which has the minimum Mahalanobis distance with the standard sample, is judged as a bid sample. The method comprises the simple steps, is convenient to operate and capable of performing fast detection, full scanning and no blind zones are realized in sample detection, the bid sample with the quality closest to that of the standard sample can be accurately identified from the bidding samples, and the method is particularly applicable to social open bidding work for the tobacco flavors.
