Method for identifying cigarettes based on acidic components of gas-phase substances of mainstream smoke of cigarettes

The invention discloses a method for identifying cigarettes based on cigarette mainstream smoke gas-phase substance acidic components. The method comprises the following steps: measuring the tar release amount of a sample cigarette, capturing the sample cigarette mainstream smoke gas-phase substance, and extracting to obtain extract liquor; carrying out GC-MS (Gas Chromatography-Mass Spectrometer) analysis on the extract liquor after derivatization, and carrying out quantitative analysis on the differential characteristic acidic components in the extract liquor to obtain the release amount of the differential characteristic acidic components; according to the difference characteristic acidic component release amount and the sample cigarette tar release amount, clustering analysis is carried out according to the obtained acid compound corrected release amount, the analysis method is simple, and the sample cigarette type is accurately identified. 本发明公开了一种基于卷烟主流烟气气相物酸性成分鉴别卷烟的方法，包括：测定样品卷烟焦油释放量、捕集样品卷烟主流烟气气相物，萃取获得萃
