Embodiment 1

[0033] (1) Preparation of internal standard solution: Accurately weigh 2.000 g of internal standard samples n-butanol (purity ≥ 99%) and 0.2000 g of 1,3-butanediol (purity ≥ 99%), use chromatographically pure isopropanol as The solvent was fixed in a 1000mL volumetric flask to obtain an internal standard solution; the concentration of the internal standard n-butanol in the internal standard solution was 2 mg / mL, and the concentration of 1,3-butanediol was 0.2 mg / mL.

[0034] (2) Preparation of standard working solution: Accurately weigh 6.000g of pure water, 3.000g of glycerin standard (purity ≥ 99%), 0.6000g of nicotine standard (purity ≥ 99%), 1,2-propanediol standard product (purity ≥ 99%) 0.6000g, glycerol triacetate standard (purity ≥ 99.5%) 0.6000g, menthol standard (purity ≥ 99%) 0.6000g, with chromatographically pure isopropanol as a solvent to constant volume in 100mL In the volumetric flask, the standard stock solution was obtained, wherein the concentration of water...

Embodiment 2

[0049] As described in Example 1, the heat-not-burn cigarette sample B was tested, and all the steps were the same as in Example 1. The contents of each target substance in the smoke aerosol of sample B are shown in Table 2 for the results.

Embodiment 3

[0051] As described in Example 1, the heat-not-burn cigarette sample C was tested, and all the steps were the same as in Example 1. The contents of each target substance in the smoke aerosol of sample C are shown in Table 2 for the results.

Abstract

The invention provides a method for detecting the smoke composition of a cigarette which is noncombustible under heating. The method comprises the following steps: (1) preparation of an internal-standard solution; (2) preparation of a standard working solution; (3) smoking of the cigarette noncombustible under heating, and collection of total particulate matters via a Cambridge filter; (4) the extraction of the total particulate matters; (5) gas chromatographic determination; and (6) calculation of determination results by using a double-internal-standard method. The method established in theinvention utilizes a traditional cigarette smoking machine for smoking of the cigarette noncombustible under heating and capturing of the total particulate matters and does not need a special smokingmachine for the cigarette noncombustible under heating; the method realizes simultaneous analysis and detection of six target components in one experiment; the method utilizes double internal standards for quantitative determination, so quantification results are more accurate; sample smoking and the capturing and extraction of the total particle particulate matters are simple to operate; and thegas chromatographic determination is convenient and stable, and has the advantages of good linear correlation, good practicality, high sensitivity, good repeatability and the like.

Description

technical field [0001] The invention relates to the technical field of tobacco detection, in particular to a method for detecting smoke components of heat-not-burn cigarettes, that is, to simultaneously detect moisture, nicotine, glycerol, 1,2-propanediol, Methods of Acetate and Menthol Delivery. Background technique [0002] Low-temperature cigarettes, also known as heat-not-burn cigarettes, heat the tobacco substance through an external heat source, and the atomization medium, flavor components and added flavors in the tobacco substance are heated to produce a smoke similar to that of traditional cigarettes. Smoke, so that consumers get physiological satisfaction. Tobacco substances in low-temperature cigarettes are only heated but not burned, and the heating temperature (250°C-350°C) is much lower than the combustion temperature (800°C-900°C) of traditional cigarettes. Therefore, the harmful components and biological toxicity of smoke are greatly reduced. Sidestream smo...
