Abstract

The invention relates to a method for analyzing components of e-cigarette smoke liquid and smoke gas. First, the standard solution of the target detection object is detected by a gas chromatography-mass spectrometer, and a standard curve is drawn by an internal standard method; Extract to obtain the test solution A, or extract the filter piece after capturing the flue gas with the extraction liquid to obtain the test solution B, after the corresponding test solution is detected by gas chromatography-mass spectrometry, calculate the test solution according to the standard curve The content of each target detection substance in the solution. By optimizing the parameter conditions of gas chromatography-mass spectrometry, the present invention can rapidly and accurately simultaneously quantitatively detect target detection substances in e-cigarette liquid and smoke, and realize rapid and accurate simultaneous determination of five target detection substances. The sensitivity of the detection method is High, good repeatability, can be widely 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 ...
