Embodiment 1

[0028] The method for simultaneously measuring 19 kinds of smoke aroma components in the heat-not-burn cigarette smoke of the present embodiment comprises the following steps:

[0029] 1) Heat the heat-not-burn cigarette of brand 1 according to the product instructions, and refer to the suction capacity and particle capture method specified in ISO 3308 for suction and particle capture. After using two Cambridge filter discs to capture the smoke particulate matter produced by 6 HNB cigarettes, put the Cambridge filter discs in a 50 mL conical flask with a stopper and lay it flat on the bottom of the bottle, add 10 mL of ethanol solution and 10 μL of internal standard solution, shake at room temperature for 20 minutes, take 2 mL of supernatant to obtain a smoke sample;

[0030] 2) GC-MS is used to detect the flue gas sample obtained in step 1);

[0031] The chromatographic conditions are: column: DB-WAXETR (60 m×0.25 mm×0.25 μm); carrier gas: He; column flow rate: 1mL / min; inle...

Embodiment 2

[0035] The method for simultaneously measuring 19 kinds of smoke aroma components in the heat-not-burn cigarette smoke of the present embodiment comprises the following steps:

[0036] 1) Heat the heat-not-burn cigarettes of brand 2 according to the product instructions, and refer to the suction capacity and particle capture method specified in ISO 3308 for suction and particle capture. After using two Cambridge filters to capture the smoke particulate matter produced by 6 heat-not-burn cigarettes, put the Cambridge filters in a 50 mL conical flask with a stopper and spread it on the bottom of the bottle, add 20 mL of ethanol solution and 20 μL of internal standard solution, shake at room temperature for 25 minutes, take 2 mL of supernatant to obtain a smoke sample;

[0037] 2) GC-MS is used to detect the flue gas sample obtained in step 1);

[0038] Chromatographic conditions and mass spectrometry conditions are the same as in Example 1.

Embodiment 3

[0041] The method for simultaneously measuring 19 kinds of smoke aroma components in the heat-not-burn cigarette smoke of the present embodiment comprises the following steps:

[0042] 1) Heat the heat-not-burn cigarette of brand 3 according to the product instructions, and refer to the suction capacity and particulate matter capture method specified in ISO 3308 for suction and particulate matter capture. After using two Cambridge filters to capture the smoke particulate matter produced by 6 heat-not-burn cigarettes, put the Cambridge filters in a 50 mL conical flask with a stopper and spread it on the bottom of the bottle, add 30 mL of ethanol solution and 30 μL of internal standard solution, shake at room temperature for 30 minutes, take 2 mL of supernatant to obtain a smoke sample;

[0043] 2) GC-MS is used to detect the flue gas sample obtained in step 1);

Abstract

The invention discloses a method for simultaneously determining 19 smoke essence components in heated non-combustion cigarette smoke. The method comprises the following steps: 1) utilizing a Cambridge filter disc to catch a particle-phase matter of the heated non-combustion cigarette smoke, then transferring the Cambridge filter disc into an extracting container, adding an internal standard solution, then adding ethyl alcohol to perform oscillation extraction and taking supernate to obtain a cigarette smoke sample; 2) utilizing GC-MS (Gas Chromatography-Mass Spectrometer) to detect the cigarette smoke sample and detecting the contents of the 19 cigarette essence components through an internal standard quantitative method. The method disclosed by the invention uses a solvent extraction-gas chromatographic mass spectrometry combined method, can simultaneously determine the contents of the 19 smoke essence components in the heated non-combustion cigarette smoke, has the advantages of quick detection, high flexibility, good selectivity and high accuracy and is especially suitable for determining the contents of the smoke essence components in the heated non-combustion cigarette smoke.

Description

technical field [0001] The invention belongs to the technical field of detection of aroma components, and in particular relates to a method for simultaneously measuring 19 types of smoke aroma components in smoke from heated non-combustion cigarettes. Background technique [0002] Heating-not-burning cigarettes are a new type of tobacco product, which can cause the contained tobacco materials to generate smoke for consumers to smoke in a non-burning state by heating. Compared with traditional cigarettes, sidestream smoke and some harmful substances are released. obviously decrease. Heat-not-burn cigarettes were first launched by Reynolds Tobacco Company. Although this type of product has not been widely recognized by the market, due to the continuous increase in tobacco control efforts around the world and its obvious advantages in reducing environmental pollution and potential health risks of smoking, The international tobacco field has always believed that this type of pr...
