Embodiment 1

[0041] Determination of the content of volatile organic compounds in the paper A for cigarette packaging. Specifically include the following steps:

[0042] (1) Standard solution preparation: accurately weigh 4mg of benzene, toluene, ethylbenzene, o-xylene, m-, p-xylene (accurate to 0.1mg); 37.5mg of methanol, isopropanol, acetone, n-propanol , butanone, ethyl acetate, isopropyl acetate, n-butanol, 4-methyl-2-pentanone, n-butyl acetate, cyclohexanone (accurate to 0.01 mg); 250 mg ethanol, 1-methoxy -2-Propanol, n-propyl acetate (to the nearest 0.1 mg). After mixing the weighed 19 kinds of VOCs, the volume was adjusted to 250 mL with the matrix calibration agent triacetin, which was designated as the first-level standard solution. Take 50.00 mL of the first-grade standard solution and add it to a 100-mL volumetric flask to dilute to the volume with triacetin, and set it as the second-grade standard solution. Take 20.00 mL of the second-grade standard solution and add it to a...

Embodiment 2

[0071] The repeatability and recovery rate of the assay method of the present invention are analyzed, and the specific steps are as follows: adding the standard working solution of 4-level and 5-level concentration gradients to the blank sample matrix of the rigid box wrapping paper A described in Example 1, and each Five spiked samples were prepared from each concentration gradient and analyzed by headspace-ion molecular reaction mass spectrometry. The average recovery and the relative standard deviation (RSD) of the measured values ​​were calculated according to the spiked amount and the measured value after spiked. The results are shown in Table 5. It can be seen from Table 5 that at the two standard addition levels, the average recovery rate of the target compound is 86.76-114.29%, and the average RSD is less than 8.40%, indicating that the method of the present invention has high accuracy and good repeatability.

Embodiment 3

[0075] Comparison of the method of the present invention and the commonly used headspace-gas chromatography / mass spectrometry (HS-GC / MS) for the determination of volatile organic compounds in smoking materials:

[0076] The hard box wrapping paper A was measured according to the method specified in the standard YC / T207-2014 "Determination of Solvent Residues in Cigarette Paper by Headspace-Gas Chromatography / Mass Spectrometry", and compared and analyzed with the measurement method and measurement results of Example 1 . The results show:

[0077] (1) Comparison of analysis time: When analyzing a single sample, the analysis time of headspace-ion molecule reaction mass spectrometry mainly depends on the headspace equilibrium time. The analysis time of the ion molecule reaction mass spectrometry section takes at most 5min, and the total time is less than 1h; The analysis time of air-gas chromatography / mass spectrometry depends on both headspace equilibration time and gas chromato...

Abstract

The invention discloses a method for determining volatile organic compounds in cigarette materials. Combining the Headspace Sampler with Ion Molecular Reaction Mass Spectrometry (IMR‑MS), the Headspace Sampler is used to collect cigarette materials (including cigarette paper, tipping paper, rigid wrapping paper, soft wrapping paper, strip packaging The volatile components in paper, cigarette filter rods and tow) are then analyzed by ion-molecular reaction mass spectrometry, and the standard curve and calculation can be used to quickly and accurately determine the content of volatile organic compounds in cigarette materials. The invention can obtain a relatively simple and clean mass spectrum, simplifies the qualitative and quantitative analysis of volatile organic compounds, and can simultaneously accurately and quantitatively detect 19 kinds of volatile organic compounds commonly found in tobacco materials, and the advantages of rapid analysis are beneficial to Realize the detection of large batches of volatile samples and meet the needs of rapid laboratory analysis.

Description

technical field [0001] The invention belongs to the technical field of compound mass spectrometry analysis, and particularly relates to a method for determining the content of volatile organic compounds in cigarette materials by using ion molecular reaction mass spectrometry technology. Background technique [0002] Tobacco materials refer to various raw materials other than shredded tobacco, which are used in the process of cigarette processing or packaging, mainly including cigarette paper, cigarette tow, filter rods, packaging materials, adhesives, filter rod plasticizers, tobacco Additives, etc., are indispensable production materials in modern cigarette production. They play an important role in the process of developing new products, adjusting product structure, reducing coke and harm, and directly affect the quality and production cost of cigarette products. . [0003] Excessive volatile organic compounds (VOCs) remaining in smoking materials not only affect the smok...
