| Abstract: |
| Ion mobility spectrometry（IMS） was used to analyze 20 kinds of counterfeit banknote paper in this article．The volatile components in counterfeit banknote papers were quickly detected by IMS，and the fingerprint spectrum library for counterfeit banknote paper was constructed．Based on principal component analysis（PCA） and hierarchical cluster analysis（HCA），the spectral information within the migration time range of 8－17.5 ms was processed，and then the counterfeit banknote papers were classified．PCA clustered the same kind of counterfeit banknote papers，while HCA further classified 20 kinds of counterfeit banknote paper accurately，and the classification accuracy rates for 6 counterfeit banknote papers of unknown origin reached 83.33%．It can help judge the source of paper used for counterfeiting．The results showed that the rapid IMS detection is an effective method for comparison and classification of counterfeit banknote papers. |
