Embodiment 1

[0021] Example 1 (The number of suction ports is 200)

[0022] A method for analyzing the nicotine transfer rate of smoke during e-cigarette smoking is as follows:

[0023] 1) Materials and methods

[0024] Prepare 2 e-cigarette samples A and B. A is a refillable cartridge type (you can add smoke oil by yourself), cigar flavor, used to study the recovery rate of the method, and verify the feasibility of the method; B is a replaceable cartridge type, Mint flavor, used to study the transfer rate of nicotine during e-cigarette smoking. After inspection, the appearance and packaging of the two electronic cigarette samples were intact, and the two sample batteries were fully charged one day before the start of the experiment.

Embodiment 2

[0056] Example 2 (The number of suction ports is 250)

[0057] A method for analyzing the nicotine transfer rate of smoke during e-cigarette smoking is as follows:

[0058] 1) Materials, reagents and instruments

[0059] Prepare e-cigarette sample D, which can replace the cartridge type and flue-cured tobacco flavor; prepare e-cigarette sample F, which is disposable, strawberry flavor. Check the appearance and packaging of the e-cigarette sample, and fully charge the sample battery one day before the start of the experiment.

Abstract

The invention provides an analysis method of a transferring rate of nicotine in smoke in an electronic cigarette smoking process. The analysis method comprises the following steps: preparing an electronic cigarette; determining the nicotine in the smoke of the electronic cigarette; determining the nicotine in a residual cigarette cartridge of the electronic cigarette; analyzing the transferring rate of the nicotine in the electronic cigarette smoking process and the like. With the adoption of the method provided by the invention, a transferring condition of the nicotine in the electronic cigarette smoking process from tobacco tar to the smoke can be objectively reflected, so that the smoking quality and quality stability of the electronic cigarette are evaluated, and theoretical evidences are provided for research and design as well as product quality control of the electronic cigarette.

Description

Technical field [0001] The invention relates to the technical field of new-type tobacco detection and analysis, in particular to a method for analyzing the nicotine transfer rate of smoke in an electronic cigarette smoking process. Background technique [0002] Since my country's Han Li patented electronic cigarettes in 2003, the global electronic cigarette market has shown an accelerated development trend. E-cigarettes can make users feel like they are smoking, because they use atomization technology without a combustion process, and the inhaled substances do not have the harmful products of traditional cigarettes such as carbon monoxide and tar. Studies have shown that electronic cigarettes can replace cigarettes and achieve the goal of quitting cigarettes gradually. Electronic cigarettes adopt the method of adding nicotine to meet the physiological needs of different smokers by adjusting the amount of nicotine added. Nicotine is one of the important components of e-cigarette...
