Abstract

The invention provides a method for detecting volatile organic compound in a cigarette filter, which comprises the following steps: a) preparing a sample; b) preparing a matrix correcting agent; c) preparing an interior label solution; d) preparing a standard sample; e) preparing a standard working solution; f) performing detection by using headspace-gas chromatography / mass-spectrography; and g) calculating a detection result of the volatile organic compound in the sample. The invention establishes the method for detecting the volatile organic compound residue in the cigarette filter for the first time. By using the saturation sodium chloride aqueous solution as the matrix correcting agent and the fluorobenzene as the interior label, the matrix effect of a solid absorption matrix (namely the cigarette filter) is efficiently reduced and the error caused by the poor repeatability of the pre-treatment and the low precision of instrument is reduced. In the whole process, no organic solvent is used. The method has the advantages of environmental friendliness, energy-saving and low consumption. The detecting method has few interference factors and good repeatability, is accurate in measuring result, is simple to operate, and can be used for obviously increasing the sensitivity of headspace analysis.

Description

technical field

[0001] The invention belongs to the technical field of physical and chemical testing of cigarette filter tip materials, and in particular relates to a technique for measuring residual amounts of thirteen kinds of volatile organic compounds in cigarette filter tips. Background technique

[0002] In recent years, the State Tobacco Monopoly Administration has continuously carried out the determination and limit standards of safety and health indicators related to smoking materials. The smoking materials involved include cigarette brand paper, tipping paper, inner lining paper, water-based glue, tow filter rods, etc. Tobacco raw materials, including 21 kinds of volatile organic compounds in restricted smoking materials (formaldehyde, methanol, ethanol, n-propanol, isopropanol, n-butanol, acetone, butanone, 4-methyl-2- pentanone, cyclohexanone, propylene glycol methyl ether, propylene glycol ethyl ether, benzene, toluene, ethylbenzene, xylene, vinyl acetate, ethyl...
