Abstract

The invention discloses a measurement method of a volatile organic compound in tobacco lining paper with high determination accuracy and good repeatability, which is suitable for simultaneously determining dozens of volatile organic compounds. The measurement method is as follows: taking fluorobenzene as an internal standard substance; using headspace gas chromatography for measuring the content of the volatile organic compound in the tobacco lining paper; wherein a detector in the headspace gas chromatography is a mass spectrometry detector. The measurement method takes the fluorobenzene as the internal standard substance, uses the headspace gas chromatography / mass spectrometry for measuring the content of the volatile organic compound in the tobacco lining paper, and has the following advantages that the fluorobenzene has stable chemical property and are very similar to determinand in every performance, and the peak time appears in the middle of 19 target VOCs to be detected; therefore, the fluorobenzene is the very suitable internal standard substance, can eliminate the influence of ground substance in the tobacco lining paper on the measurement, causes materials which can not or are difficult to peak to be measured, and has high measurement accuracy and few interference factors.

Description

technical field

[0001] The invention relates to a method for measuring volatile organic compounds in inner lining paper for cigarettes, and belongs to the technical field of physical and chemical testing of cigarette packaging materials. Background technique

[0002] Some volatile organic compounds (VOCs) remain in the printed products of cigarette packaging, and they are one of the main sources of potential pollutants. Cigarette lining paper is the packaging material that is in direct contact with cigarettes, and the residual volatile organic compounds will affect the smoking safety and quality of cigarettes.

[0003] At present, the determination method of volatile organic compounds in cigarette packaging materials is mainly the external standard method. The limit of volatile organic compounds, and the method in the YC / T207-2006 "Determination of Volatile Organic Compounds in Cigarette Rod and Packing Paper" standard is used as a reference method for the detection of vola...
