Abstract

A method for measuring main carbonyl compounds in a main stream smoke of a cigarette through ultra high performance convergence chromatography is a method for measuring butyraldehyde, 2-butanone, propionaldehyde, crotonaldehyde, acrolein, acetone, acetaldehyde and formaldehyde in the main stream smoke. The method is characterized in that a filter leaf processed with a derivatization reagent is used to gather the main carbonyl compounds in the main stream smoke of the cigarette, the analyzing and measuring method is used to obtain the contents of the eight carbonyl compounds in the main stream smoke through ultra high performance convergence chromatography (UPC2). When the method provided by the invention is used to detect the contents of the main carbonyl compounds in the main stream smoke of the cigarette rapidly and effectively, the pretreatment is simple, the average relative standard deviation is less than 7%, and the average recovery rate of various indexes is between 75%-94%. The method has the advantages of rapidness, accuracy, high flexibility and good repeatability.

Description

[0001] technical field [0002] The invention belongs to the technical field of physical and chemical testing of cigarette mainstream smoke, and specifically relates to a method for measuring main carbonyl compounds (butyraldehyde, 2-butanone, propionaldehyde, crotonaldehyde, acrolein) in cigarette mainstream smoke by using ultra-high performance convergence chromatography. , acetone, acetaldehyde, formaldehyde), the method is fast, efficient, and environmentally friendly, which is conducive to improving the detection efficiency of carbonyl compounds in cigarette mainstream smoke, while greatly reducing the loss of organic solvents and reducing environmental pollution. Background technique [0003] Carbonyl compounds are an important class of harmful components in mainstream cigarette smoke. They are included in the Canadian government's list of 46 harmful components and the list of controlled components recommended by the WHO "Tobacco Product Regulation Research Group", thus...
