Problems solved by technology

[0003] At present, the research on nicotine in e-cigarette smoke is focused on the establishment of detection methods. There has been no effective research and analysis method for the change of nicotine in e-cigarette smoke during the smoking process, resulting in the evaluation of e-cigarette smoking. Insufficient theoretical basis for quality and quality stability, insufficient scientific and comprehensive evaluation

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 novel tobacco detection and analysis, in particular to an analysis method for the nicotine transfer rate of smoke during the smoking process of electronic cigarettes. Background technique [0002] Since my country's Han Li invented the e-cigarette patent in 2003, the global e-cigarette market has shown a trend of accelerated development. E-cigarettes can make users feel like they are smoking, because they use atomization technology without combustion process, and the inhaled substances do not have harmful products such as carbon monoxide and tar in traditional cigarettes. Studies have shown that electronic cigarettes can replace cigarettes and achieve the goal of gradually quitting cigarettes. 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 ...
