Embodiment 1

[0039]The cigarettes used are flue-cured cigarettes. Take one cigarette sample each, and balance it under the conditions specified in GB / T 16447. Select the cigarettes with an average weight of ±0.02 g and an average draw resistance of ±49 Pa as the sample cigarettes. In YC / T 29 Smoking was carried out with a linear smoking machine under specified conditions, and 44 mm Cambridge filter discs were used to collect the total particulate matter of 4 cigarettes per filter disc. After suctioning, take out the filter piece and put it into a 100 mL Erlenmeyer flask; add 40 mL ethanol solution containing internal standard (1,3-butanediol) for ultrasonic extraction for 30 min, and filter the extract with a 0.45 μm microporous membrane. For instrumental analysis. Simultaneously, the standard recovery experiment was carried out.

[0040] The analysis conditions of gas chromatography-mass spectrometry were: HP-Inno WAX strong polar capillary column (30 m × 250 μm i.d. × 0. 25 μm d.f.). I...

Embodiment 2

[0043] The cigarettes used are e-cigarettes, and the conditions stipulated by the Canadian deep smoking model are used; the smoke is smoked with a linear smoking machine, and the smoke is collected with a 44 mm Cambridge filter, and each filter collects the total particle phase of 4 cigarettes things. After suctioning, take out the filter piece and put it into a 100 mL Erlenmeyer flask; add 40 mL ethanol solution containing internal standard (1,3-butanediol) for ultrasonic extraction for 30 min, and filter the extract with a 0.45 μm microporous membrane. For instrumental analysis. Simultaneously, the standard recovery experiment was carried out.

[0044] The gas chromatographic analysis conditions were as follows: HP-Inno WAX strong polar capillary column (30 m × 250 mu m i.d. × 0. 25 mu m d.f.). The injection port temperature was 250 °C; temperature program: 110 °C (hold 1 min), 5 °C / min to 200 °C (3 min), then 30 °C / min to 230 °C (3 min). A hydrogen flame detector was...

Embodiment 3

[0047] The cigarettes used are low-temperature cigarettes, and the conditions stipulated by the Canadian deep smoking model are adopted; the smoke is smoked with a linear smoking machine, and the smoke is collected with a 44 mm Cambridge filter, and each filter collects the total particle phase of 4 cigarettes things. After suctioning, take out the filter piece and put it into a 100 mL Erlenmeyer flask; add 40 mL and use ethanol solution containing internal standard (1,3-butanediol) for ultrasonic extraction for 30 min, and filter the extract with a 0.45 μm microporous membrane , for instrumental analysis. Simultaneously, the standard recovery experiment was carried out.

[0048] The analysis conditions of gas chromatography-mass spectrometry were: HP-Inno WAX strong polar capillary column (30 m × 250 μm i.d. × 0. 25 μm d.f.). Injection port temperature 250 °C; temperature program: 110 °C (hold for 1 min), rise to 200 °C at 5 °C / min (hold for 3 min), then rise to 230 °C at 3...

Abstract

The invention discloses a method for measuring glycerinum and 1,2-propylene glycol in cigarettes, electronic cigarettes and low-temperature cigarettes. The method comprises cigarette suction, smoke capturing, sample extraction and instrumental analysis and specifically comprises the steps: (1) sucking the cigarettes, the electronic cigarettes and the low-temperature cigarettes through a range hood; (2) capturing components to be measured in mainstream smoke through a Cambridge filtering disk or an absorption bottle; (3) adding a solvent into the Cambridge filtering disk with the components to be measured for extraction; (4) filtering an extracting solution or an absorption solution in the absorption bottle for analysis and determination through an instrument. The method is high in reproducibility and high in analysis sensitivity and can be used for accurately and quantitatively analyzing the glycerinum and the 1,2-propylene glycol in the cigarettes, the electronic cigarettes and the low-temperature cigarettes. The method is easy to operate, and a measurement result is accurate; therefore, the industrial standard for evaluation and monitoring of the quality of a cigarette product is further perfected.

Description

technical field [0001] The invention belongs to the technical field of measuring methods for chemical components of tobacco, and in particular relates to a measuring method for glycerin and 1,2-propanediol in cigarettes, electronic cigarettes and low-temperature cigarettes. Background technique [0002] Glycerin and 1,2-propanediol are the most commonly used humectants in cigarettes, and they are also important components in cigarette smoke. The pods of low-temperature cigarettes and electronic cigarettes also contain a large amount of glycerin or 1,2-propanediol, which are the most commonly used "medium" for the formation of "smoke" in electronic cigarettes and low-temperature cigarettes, and are also the smoke aerosols of electronic cigarettes and low-temperature cigarettes Therefore, the accurate determination of glycerol and 1,2-propanediol in the mainstream smoke of cigarettes, electronic cigarettes and low-temperature cigarettes is of great significance for the quality...
