The odors of the entire box unopened the filter the cut tobacco the cigarette paper and the smoke were respectively tested by PEN3 electronic nose and the method of PCA and the method of PCA +LDA were used to analyze the information of the five different odors. Finally experimental samples were tested based on the odor information of the entire box using correlation analysis. The results showed that the three levels could be discriminated from the information of the five different odors respectively with the effects from superior to inferior followed by the filter the smoke the entire box the cut tobacco the cigarette paper. The accuracy of testing the entire box samples by correlation analysis reached 100%.
