Embodiment 1

[0024] The reagents used in this example are: adhesive for cigarettes; acetone, methyl acetate, tert-butanol, ethyl acetate, methanol and butyl acetate, all of analytical grade.

[0025] The instruments used in this example are: GC9800 gas chromatograph (Shanghai Kechuang Chromatographic Instrument Co., Ltd.); DK-3001A type headspace sampler, headspace bottle and manual capper (Beijing Zhongxing New Technology Research Institute of Analytical Instruments) .

[0026] The headspace conditions were set as follows: the heating temperature of the headspace bottle was 100°C, the sample loop temperature was 120°C, the transfer line temperature was 140°C, and the sample equilibration time was 30min.

[0027] The gas chromatograph is set as follows: the chromatographic column is a 60m×0.32mm×1.8μm DB-624 chromatographic column; the carrier gas is high-purity nitrogen (purity greater than 99%), and the column pressure is 0.05MPa; the inlet temperature: 260°C; FID detector temperature: ...

Abstract

The invention discloses a method for detecting organic volatile matters in adhesive for cigarettes. Headspace gas chromatography is adopted in the method and comprises the following steps of: weighing a sample to be detected, putting in a headspace sample introduction bottle, sealing the headspace bottle, balancing the headspace bottle for 30 to 40 minutes at the temperature of between 100 and 120 DEG C, extracting air in the bottle, and performing gas chromatography, wherein the column temperature conditions of a gas chromatograph comprise that the initial temperature is 50 DEG C and kept for 2 minutes, the temperature is raised to 60 DEG C at the rate of 1 DEG C per minute, the heat is preserved for 5 minutes, then the temperature is raised to 120 DEG C at the rate of 3 DEG C per minute, and the heat is preserved for 5 minutes. The method is used for analyzing organic residues in the adhesive for the cigarettes, and is simple, convenient, quick and good in reproducibility.

Description

technical field [0001] The invention relates to the field of organic matter detection, in particular to a headspace gas chromatography for organic matter detection. Background technique [0002] Organic volatile substances in tobacco adhesives, that is, organic residues (methanol, acetone, methyl acetate, tert-butanol, vinyl acetate, ethyl acetate, etc.) are introduced by the raw materials themselves. bodies and organic solvents. Organic residues will cause bad smell in cigarette adhesives, and methanol, acetone, etc. are harmful compounds to the human body. Too much content will cause great harm to the human body, such as carcinogenic and mutagenic. In today's society, people are paying more and more attention to health, which leads to the trend of "green" and "harmless" tobacco materials. Therefore, the research and development of effective, fast and accurate analysis and testing methods for organic residues is very important for ensuring the quality of cigarette products...
