Embodiment 1

[0034] The trapping device that the present invention adopts is as figure 1 As shown, put the 44 mm Cambridge filter into the filter holder, the rough side of the filter should face the incoming flue gas, close the filter holder, and check that it is properly assembled. If the e-cigarette can be put into one end of the trap during the smoking process, and there is no air leakage, then directly insert the e-cigarette into the trap for puffing. But now commercially available e-cigarette nozzles have different shapes. If one end of the trap does not match the e-cigarette nozzle and air leakage occurs during the suction process, it is necessary to add an adapter with good airtightness between the trap and the e-cigarette. , to prevent air leakage during suction.

[0035] Two 30mL dichloromethane absorption bottles are connected in series between the smoking machine trap and the suction syringe, and the absorption bottles are put into the heat preservation barrel for ice-salt bath...

Abstract

The invention relates to a determination method of aroma components in an electronic cigarette aerosol, and belongs to the technical field of assay determination. According to the method, a Cambridge filter is used for collecting grain phase compositions in the electronic cigarette aerosol, absorption bottles collect gas phase compositions in the electronic cigarette aerosol in cold trap conditions, then ultrasonic extraction is carried out by using dichloromethane, and deionized water is combined to carry out liquid-liquid back-extraction, the interference of large amounts of alcohol in the aerosol is eliminated, finally, the gas chromatography mass spectrometry is combined to perform qualitative and quantitative analysis. With the adoption of the determination method of the aroma components in the electronic cigarette aerosol disclosed by the invention, loss or decomposition of volatile aroma components in the electronic cigarette aerosol can be effectively avoided, multiple volatile aroma components can be simultaneously analyzed, the repeatability is better, the sensitivity is high and the operation is simple, and the interference of matrix components and solvents can be avoided, so that the determination method of the aroma components in the electronic cigarette aerosol has certain advantages in detection of the volatile aroma components in the electronic cigarette aerosol.

Description

technical field [0001] The invention belongs to the technical field of analysis and measurement, and relates to a measurement method, in particular to a method for measuring and analyzing aroma components in electronic cigarette aerosol. Background technique [0002] New tobacco products are strategic products of the tobacco industry and an important direction for the future development of the tobacco industry. E-cigarette is a new type of tobacco product that has developed most rapidly in recent years. It uses electric heating to atomize the liquid in the e-cigarette into a mixed gas containing propylene glycol / nicotine for smokers to inhale. This heating atomization method of electronic cigarettes not only replaces the burning of traditional cigarettes, but also greatly reduces the harmful substances produced by burning. The hazards of passive smoking caused by second-hand smoke to non-smokers. The e-cigarette market at home and abroad has experienced explosive growth si...
