Abstract

The invention relates to an electronic cigarette liquid and smoke component analysis method; the method comprises the following steps of firstly, carrying out gas chromatography-mass spectrometer combined instrument detection on a standard solution of a target detection object, and drawing a standard curve by an internal standard method; and extracting a tobacco liquid sample by using an extracting solution to obtain a to-be-detected liquid A, or extracting a filter sheet after trapping the smoke by using an extracting solution to obtain a to-be-detected liquid B, and carrying out gas chromatography-mass spectrometer combined instrument detection on the corresponding to-be-detected liquid, and calculating the content of each target detection substance in the liquid to be detected accordingto the standard curve. According to the method, the gas chromatography-mass spectrum parameter condition is optimized, so that the target detection substances in the electronic cigarette liquid and smoke can be detected rapidly and accurately at the same time, and the detection method is high in sensitivity and high in repeatability, and can be widely popularized and used.

Description

technical field [0001] The invention relates to a method for analyzing electronic cigarette liquid and smoke components, belonging to the technical field of electronic cigarette and tobacco analysis Background technique [0002] At present, the existing e-cigarettes are becoming more and more common in the market, and their tastes are also diversified. The more common ones are tobacco aroma and fruit aroma. Spices, additives, etc. The main components in the e-cigarette liquid are propylene glycol and glycerin. If the purity of the propylene glycol and glycerin solvents is not up to the standard, there will be a certain amount of solvent residue, which will affect the quality of the e-cigarette liquid. Moreover, affected by environmental factors, such as light, temperature, etc., during the storage of e-cigarette liquid, propylene glycol, glycerin and other components have some slow chemical reactions among themselves or each other, and some substances will be produced. At ...
