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 device for a cigarette tipping paper anti-adhesion test is disclosed. The device includes the following components: an upper cover (), a plurality of upper cover semi-cylinders () inside the upper cover, having the same radius and arranged in parallel, and a box () with a plurality of holes () on the box upper surface (), connected with the inner cavity of the box (). Each upper cover semi-cylinder has a cross-section with a bow shape. The side wall of the box () also has an opening (). A method for testing anti-adhesion of the cigarette tipping paper using the device is also disclosed. The present device can qualitatively and quantitatively simulate adhesion of tipping paper in various conditions.
