Embodiment 1

[0077] Embodiment 1, the establishment of the standard curve of volatile organic gases

[0078] 1. Establishment of standard curve

[0079] Using methanol as a solvent, configure 1,3-butadiene standard solution with concentration gradient, isoprene standard solution with concentration gradient, benzene standard solution with concentration gradient and toluene standard solution with concentration gradient product solution.

[0080] The concentration gradient of 1,3-butadiene standard solution with concentration gradient is 1 μg / mL, 5 μg / mL, 10 μg / mL, 20 μg / mL, 30 μg / mL and 50 μg / mL.

[0081] The concentration gradient of the isoprene standard solution with concentration gradient is 1 μg / mL, 5 μg / mL, 10 μg / mL, 20 μg / mL, 30 μg / mL and 50 μg / mL.

[0082] The concentration gradient of the benzene standard solution with a concentration gradient is 1 μg / mL, 5 μg / mL, 10 μg / mL, 20 μg / mL, 30 μg / mL and 50 μg / mL.

Embodiment 2

[0118] Example 2. Detection of the content of volatile organic gases in the vapor of electronic smog

[0119] Two absorbing bottles containing absorbing liquid are connected in series and placed in an isopropanol-dry ice cold trap at a temperature of -70°C. The smoke is connected, and the smoke sampling tube is provided with a filter plate near the end of the passage where the vapor of the electronic cigarette flows through. The smoking simulation device sucks the electronic cigarette, and the absorption bottle containing the absorption liquid collects the vapor of the electronic cigarette evaporated by the electronic cigarette. The puff parameters of the smoking simulation device are specifically: the duration of each puff is 3s, the volume of each puff is 55mL, the interval between puffs is 30s, and each test sample corresponds to 50 puffs.

[0120] The puff parameters of the smoking simulation device are as follows: the duration of each puff is 3s, the volume of each puff i...

Abstract

The invention discloses a method for detecting the content of volatile organic gas in atomized steam of an electronic cigarette, comprising the following steps: collecting atomized steam of the electronic cigarette evaporated from the electronic cigarette by using an absorption bottle filled with an absorption solution; adding a detecting internal standard to the absorption solution in which the atomized steam of the electronic cigarette is collected to obtain a sample solution; respectively performing chromatographic detection and mass spectrometric detection on the sample solution, putting the detecting results into a standard curve of the volatile organic gas for calculation, and acquiring the content of the volatile organic gas in the atomized steam of the electronic cigarette through commutation. According to the method for detecting the content of volatile organic gas in atomized steam of an electronic cigarette, the volatile organic gas in the atomized steam of the electronic cigarette is absorbed by using the absorption bottle filled with the absorption solution to obtain the sample solution, then the sample solution is detected by an internal standard method, and the content of volatile organic gas in the atomized steam of the electronic cigarette is obtained through commutation. The method for detecting the content of volatile organic gas in atomized steam of the electronic cigarette is simple and highly efficient.

Description

technical field [0001] The invention relates to the field of electronic cigarettes, in particular to a method for detecting the content of volatile organic gases in vapors of electronic cigarettes. Background technique [0002] In recent years, with the increasing number of signatories of the "World Health Organization Framework Convention on Tobacco Control", the intensity of tobacco control in the world has continued to increase, and people's health awareness has increased, represented by electronic cigarettes, snus, and low-temperature cigarettes. New tobacco products have achieved rapid development. [0003] E-cigarette is an electronic device that converts e-liquid into smoke through an atomizer and delivers nicotine and other substances to the respiratory system. As a substitute for traditional cigarettes, it has developed rapidly in recent years. E-cigarettes are generally composed of a smoke tube, an atomizer and a battery. The atomization core or atomization wire a...
