Abstract

The invention discloses a method for detecting the content of nicotine in smoke of an electronic cigarette. The detection method comprises the following steps: (1) preparing an extracting agent; (2) preparing a standard series solution of the nicotine; (3) connecting a Cambridge filter and an absorption bottle with a smoking machine in series and capturing the smoke of the electronic cigarette; putting the Cambridge filter for capturing the smoke and absorption liquid into a tapered bottle and carrying out vibration extraction; (4) moving away an extracting liquid filtering membrane and analyzing filter liquid by using a gas chromatographic method; and (5) drawing a standard curve and calculating the content of the nicotine in the smoke of the electronic cigarette. The method disclosed by the invention has the advantages of high sensitivity, good selectivity, simplicity in operation and high repeatability, and can realize the accurate quantitative analysis of the nicotine in the electronic cigarette.

Description

technical field [0001] The invention relates to the technical field of physical and chemical testing of smoke from electronic cigarettes, in particular to a method for detecting nicotine content in smoke from electronic cigarettes. Background technique [0002] As the global tobacco control environment is becoming increasingly severe and consumers are increasingly concerned about health, breaking through traditional cigarette technology and developing an electronic cigarette that comprehensively and significantly reduces the release of harmful tobacco components has gradually become a solution for the future development of the tobacco industry in various countries. important means. Electronic cigarettes, also known as electronic nicotine delivery systems (ENDS). The official definition of electronic nicotine delivery systems by the World Health Organization (WHO technical report series 955, P4-5) is: An electronic nicotine delivery system (ENDS) is a consumer product that d...
