Embodiment 1

[0027] Example 1: Take a certain brand of e-cigarette samples, use a straight-line smoking machine to smoke in ISO mode, and use a channel trap without e-cigarettes as a blank sample for nicotine determination.

[0028] According to the method described in the above technical solution of the present invention, the nicotine in the smoke emission after the electronic cigarette is smoked continuously for 50 puffs is measured.

[0029] The extractant for extracting nicotine on the Cambridge filter was 20 mL of isopropanol containing 0.2-0.5 mg / mL n-heptadecane as an internal standard.

[0030] The absorbent in the absorption bottle is 20 mL of isopropanol containing 0.2-0.5 mg / mL n-heptadecane as internal standard.

[0031] The nicotine content in the extraction liquid and the absorption liquid was determined by gas chromatography. The analysis conditions are: chromatographic column: fused silica capillary column alkali-deactivated polyethylene glycol stationary phase (Stabilowax...

Embodiment 2

[0035] Example 2: Take a certain brand of e-cigarette samples, use a linear smoking machine to smoke in ISO mode, and use a channel trap without e-cigarettes as a blank sample for the determination of propylene glycol and glycerin.

[0036] According to the method of the present invention, the propylene glycol and glycerin in the smoke emission after the electronic cigarette is smoked continuously for 50 puffs are detected.

[0037] The extraction solvent for propylene glycol and glycerol on the Cambridge filter was 20 mL of ethanol solution containing internal standard (1,3-butanediol).

[0038] The absorption liquid in the absorption bottle is 20 mL ethanol solution containing internal standard (1,3-butanediol).

[0039] The contents of propylene glycol and glycerol in the extract and absorption liquid were determined by gas chromatography-mass spectrometry. The analysis conditions were as follows: chromatographic column: HP-Inno WAX strong polar capillary column (30 m × 25...

Abstract

The invention relates to a method for capturing main components, such as nicotine, glycerinum, propylene glycol, aldehydes and volatile organic compounds, in smoke releasing substances of an electronic cigarette. The method comprises the following steps of smoking an electronic cigarette sample by adopting a linear smoking machine according to an ISO smoking mode, and capturing particle phase parts in the smoke releasing substances through a 44mm cambridge filter. A cold trap capturer is connected between a capturer and a smoking needle barrel of the smoking machine and is used for capturing a gas phase component penetrating through the cambridge filter; the particle phase part captured by the cambridge filter is subjected to ultrasonic extraction, and the amount of target analytes in capturing liquid and the amount of target analytes in extracting liquid are respectively measured; the total amount of the main target analytes in the smoke releasing substances in the electronic cigarette is calculated. According to the capturing of the main components in the smoke releasing substances of the electronic cigarette, the capturing is comprehensive, the capturing efficiency is high, and the accuracy and the scientificity of main component detection for the smoke releasing substances of the electronic cigarette are improved.

Description

technical field [0001] The invention relates to a method for capturing main components in smoke emissions from electronic cigarettes. technical background [0002] With the continuous development of the global tobacco control movement, in order to meet the needs of different consumers, various imitation cigarette products are emerging. E-cigarettes are a new type of tobacco product that has developed the fastest in recent years. Alkali, flavoring substances and other mixtures make people inhale nicotine in different doses. E-cigarettes are electronic delivery devices that deliver nicotine to the respiratory system by means of electronic heating. As a substitute for cigarettes, e-cigarettes are very similar in appearance to real cigarettes. It simulates the taste of cigarettes, but has no ash, no cigarette butts, no burning, no open flame, and no tar, carbon monoxide, hydrocyanic acid, acrolein, arsenic, lead, mercury and other harmful substances. In addition, the nicotin...
