A method of identifying tobacco carbonyl components using non-targeted mass spectrometry is disclosed, which includes the following steps: (1) preparing a tobacco sample extract; (2) derivatizing (part of) the sample/extract with 2,4-dinitrophenylhydrazine (DNPH); (3) derivatizing (another part of) the sample/extract with DNPH-d; (4) mixing the derivatized tobacco samples; (5) preparing blank samples; (6) performing ultra performance liquid chromatography (UPLC) and ion trap (Orbitrap) high resolution mass spectrometry (HRMS) on the (derivatized) tobacco samples; (7) processing the LC-MS data; (8) filtering the mass spectrometric characteristic data to retain final chromatographic peaks; and (9) structurally annotating or identifying the retained final chromatographic peaks to obtain the tobacco carbonyl components. The method quickly removes noise or interfering components in the original data set by multiple filtering of the mass spectrometry characteristic data, and enables obtaining composition information of aldehyde and ketone chemical components in cigarettes.

A determination method for lip sticking force of cigarette tipping paper is provided. The artificial saliva is used to clamp the tipping paper and the artificial mouth skin that are bonded between two jigs, respectively. The two jigs move relative to each other. Force changes during the test are collected through a force sensor and a displacement sensor.
