Embodiment 1

[0025] Weigh 0.0500g of acetone, isopropanol and methyl acetate standard products respectively, place them in a 1000mL volumetric flask, and dilute to the mark with chromatographically pure dimethylformamide, and this solution is the mixed standard stock solution. Accurately pipette 2mL, 4mL, 8mL, 16mL, and 32mL of the mixed standard stock solutions, place them in 100mL volumetric flasks, and dilute to the mark with chromatographically pure dimethylformamide to obtain a series of standard working solutions. Concentrations of the prepared serial mixed standard solutions are: 1mg / L, 2mg / L, 4mg / L, 8mg / L, 16mg / L.

[0026] Cut up the hot melt adhesive sample A, weigh 0.2000g and place it in a headspace bottle, accurately add 2mL of dimethylformamide, and analyze it by headspace-gas chromatography-mass spectrometer. The headspace conditions are: sample bottle equilibrium temperature: 120°C, sample loop temperature: 140°C, transfer line temperature: 180°C; sample vial equilibration t...

Embodiment 2

[0032] As described in Example 1, select another hot melt adhesive sample B, attached Figure 5 It is the chromatogram of hot melt adhesive sample B for cigarettes. The sample was measured twice, and the average value was obtained to obtain that the acetone content in sample B was 12.94 mg / L, the isopropanol content was 7.78 mg / L, and the methyl acetate content was 9.33 mg / L.

Abstract

The invention provides a method for detecting volatiles residue in hot-melt adhesive for cigarettes; the method comprises the steps of (1) preparing a standard working solution for various volatiles; (2) preparing a sample; (3) determining by headspace-gas chromatography / mass spectrometry process; (4) calculating measurement results for various volatiles in the sample. The method is simple and convenient, and ingredient loss due to complex pre-treatment is avoided; dimethyl formamide is selected as a matrix corrective, matrix effect can be relieved, all volatiles to be detected can be dissolved, and the ingredients to be detected can also be detected without influence; the method has the advantages of good operation accuracy, high sensitivity and good repeatability.

Description

technical field [0001] The invention belongs to the technical field of tobacco analysis, and in particular relates to a method for detecting residues of volatile components in hot melt adhesives for cigarettes. Background technique [0002] The residual volatile components in the hot melt adhesive for cigarettes are introduced by the raw materials themselves, mainly residual monomers and organic solvents. The working temperature of hot melt adhesive for cigarettes is high. It is applied in a molten state, and then cooled to a solid state to complete the bonding. The volatile components generated in the molten state accumulate in the cigarette filter, causing bad smell, affecting the taste of cigarettes, and reducing the quality of cigarettes. . Secondly, volatile components such as acetone, isopropanol, and methyl acetate are harmful to the human body, and the safety of smoking materials has always been the focus of the tobacco industry. Therefore, it is of great significa...
