Abstract

The invention provides a detection method of alcohol compounds (1,2-propylene glycol, glycerol and menthol), phenols and free nicotine in mainstream smoke of heat-not-burn cigarettes. The detection method comprises the following steps: (1) preparing a test sample solution, including capturing the alcohol compounds in the mainstream smoke of the heat-not-burn cigarettes by using a filter; (2) preparing a standard solution; (3) measuring the content of the alcohol compounds in the mainstream smoke of the heat-not-burn cigarettes with gas chromatography under the conditions that a chromatographiccolumn and a CP-1301 silica gel column capillary column are included. The content of the main alcohol compounds (1,2-propylene glycol, glycerol and menthol), phenols and free nicotine in the mainstream smoke of the heat-not-burn cigarettes can be detected accurately, efficiently and environmentally friendly with the method.

Description

technical field [0001] The invention relates to the technical field of analytical chemistry, in particular to a method for detecting 1,2-propanediol, glycerol and menthol in mainstream smoke of heat-not-burn cigarettes; and a method for detecting phenolic compounds in mainstream smoke of heat-not-burn cigarettes A detection method; a detection method for free nicotine in the mainstream smoke of heat-not-burn cigarettes. Background technique [0002] Heat-not-burn tobacco products (HNB) refer to smoking through heat-not-burn tobacco products, and the chemical components in the cigarettes are vaporized to generate smoke, so as to meet people's smoking needs. Since the heat-not-burn tobacco product is only heated (not burned) to vaporize or crack the substances in the cigarette, there are fewer harmful substances in the mainstream smoke of the heat-not-burn tobacco product. Among them, polyol compounds such as 1,2-propanediol and glycerin can maintain the moisture of tobacco p...
