Abstract

The invention discloses a method for measuring main carbonyl compounds in a cigarette filter through ultra-performance convergence chromatography, namely a method for measuring butyraldehyde, 2-butanone, propionaldehyde, crotonaldehyde, acraldehyde, acetone, acetaldehyde and formaldehyde in the cigarette filter. The method is characterized in that the smoked cigarette filter is analyzed and measured through the ultra-performance convergence chromatography (UPC2), so that the contents of eight carbonyl compounds in the filter can be obtained. According to the method, the shortcomings in the conventional detection method in the prior art are overcome, and the detection conditions of an instrument are optimized; the method disclosed by the invention can be used for quickly and effectively detecting the contents of the main carbonyl compounds in the cigarette filter; pretreatment is simple; the average relative standard deflection is less than 10 percent; the average recycling rate of all indexes is 88-101 percent. The method has the advantages of quickness, accuracy, high sensitivity and high in repetitiveness.

Description

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