preparation example Construction

[0068] The second aspect of the present invention provides a method for preparing a sampling tube for detecting carbonyl compounds in vaporization vapor of electronic cigarettes, comprising the following steps:

[0069] (1) Take a tube body with two open ends, fill the inside of the tube body with silica gel particles, and then seal the two ends of the silica gel particles with loose fillers;

[0070] (2) Adding a derivatization reagent to the tube body, so that the surface of the silica gel particle adsorbs the derivatization reagent;

[0071] (3) Drying the tube body and removing the liquid in the tube body to obtain a sampling tube for detecting carbonyl compounds in the vaporization vapor of the electronic cigarette.

[0072] In one embodiment of the present invention, the material of the tube body is organic glass, quartz glass or transparent resin.

[0073] In a preferred embodiment of the present invention, the transparent resin can be polymethyl methacrylate (PMMA), p...

Abstract

The invention provides a sampling pipe for detecting carbonyl compounds in electronic atomization steam of an electronic cigarette as well as a preparation method and an application of the sampling pipe. The sampling pipe comprises a pipe body with two open ends, wherein the inside of the pipe body is filled with silica-gel particles, two ends of each silica-gel particle are blocked with degreasing cotton, and derivatization reagents capable of being subjected to a derivatization reaction with carbonyl compounds are adsorbed on surfaces of the silica-gel particles. The sampling pipe is simple in structure, relatively small in size and capable of preserving the carbonyl compounds for a long time and has great practical popularization and application value. The invention further provides a preparation method of the sampling pipe for detecting the carbonyl compounds in electronic atomization steam of the electronic cigarette, the method is simple and easy to operate and suitable for large-scale production of the sampling pipe. The invention further provides an application of the sampling pipe in quantitative detection of the carbonyl compounds in the atomization steam of the electronic cigarette, the sampling process and the follow-up analysis process are simple, the analysis time is relatively short, and the sampling pipe can detect the content of the carbonyl compounds in the atomization steam of the electronic cigarette accurately.

Description

technical field [0001] The invention relates to the technical field of physical and chemical testing of electronic cigarette products, in particular to a sampling tube for detecting carbonyl compounds in vaporization vapor of electronic cigarettes, a preparation method and application thereof. Background technique [0002] An electronic cigarette is an electronic device that converts e-liquid into atomized vapor through an atomizer, and delivers nicotine and other substances to the respiratory system. Volatile carbonyl compounds are an important class of harmful substances in the vaporization of electronic cigarettes. Foreign countries have carried out related research work as early as the 1920s, and included such compounds in the "Hoffman List" of 44 harmful components . Among them, low-molecular carbonyl compounds (mainly formaldehyde, acetaldehyde and acrolein) have cilia toxicity and will stimulate the human respiratory system and sensory organs to varying degrees durin...
