At present, the classification and confirmation of tobacco leaf grades mainly rely on human beings to comprehensively judge the differences in tobacco leaf color, shape, feel, and smell, that is, to judge the internal quality based on the appearance, so the accuracy is not good, and the judgment results still vary from person to person. It is difficult to accurately unify the standard

The invention discloses a method for identifying the grade of tobacco leaves by utilizing a field asymmetric waveform ion mobility spectrometry analysis technology. The method is applied to a tobaccoleaf processing industry and a field asymmetric waveform ion mobility spectrometry (hereinafter referred to as FAIMS) is a gas-phase ion separation technology developed on the basis of a traditional ion mobility spectrometry. According to the method disclosed by the invention, an FAIMS detection technology is used for detecting volatile components of the tobacco leaves; the grade of the tobacco leaves is judged through establishing an FAIMS pattern model of the volatile components with different grades of the tobacco leaves and comparing a sample detection pattern with a model pattern.
Description
technical field [0001] The invention relates to a method for identifying the grade of tobacco leaves using a high-field asymmetric ion mobility spectrometry analysis technique. Background technique [0002] Tobacco leaf grade classification is mainly used for tobacco leaf quality classification. At present, the classification and confirmation of tobacco leaf grades mainly rely on human beings to comprehensively judge the differences in tobacco leaf color, shape, feel, and smell, that is, to judge the internal quality based on the appearance, so the accuracy is not good, and the judgment results still vary from person to person. It is difficult to accurately unify the standard. Some advanced cigarette companies have begun to use the near-infrared rapid chemical composition detection technology to detect the solid matter division components of tobacco leaves to assist in the determination of tobacco leaf grades. However, due to the quality characteristics of tobacco leaves, ...
