Embodiment 1

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

[0042] (1) Preparation of standard solution: Accurately weigh 4mg of benzene, toluene, ethylbenzene, o-xylene, m-xylene, 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 0.01mg); 250mg ethanol, 1-methoxy -2-propanol, n-propyl acetate (accurate to 0.1 mg). After mixing the 19 kinds of VOCs that were weighed, the volume was adjusted to 250mL with triacetin triacetin as a matrix calibrator, and it was defined as the first-level standard solution. Take 50.00mL of the first-level standard solution and add it to a 100mL volumetric flask to make up the volume with glycerol triacetate, and set it as the second-level standard solution. Take 20.00mL of the second-level standard solu...

Embodiment 2

[0071] The repeatability and the rate of recovery of assay method of the present invention are analyzed, and its concrete steps are: add the standard working solution of 4 grades and 5 grades of concentration gradient respectively in the blank sample matrix of hard box packing paper A described in embodiment 1, every 5 spiked samples were made in each concentration gradient, and the headspace-ion molecular reaction mass spectrometry was carried out respectively, and the average recovery rate and the relative standard deviation (RSD) of the measured value were calculated according to the spiked amount and the measured value after the spiked value. The results are shown in Table 5. It can be seen from Table 5 that the average recovery rate of the target compound is 86.76-114.29% and the average RSD<8.40% at the two spiked levels, indicating that the method of the present invention has high accuracy and good repeatability.

Embodiment 3

[0075] The comparison between 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 tobacco materials:

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

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

Abstract

The invention discloses a method for measuring a volatile organic compound in a tobacco material. The method comprises the steps of using a headspace sampler and ion molecular reaction mass spectrometry (IMR-MS) in a combination way, collecting a volatile constituent in tobacco material paper (including cigarette paper, tipping paper, hard box package paper, soft box package paper, strip package paper, tobacco filter stick and filaments by a headspace sampler, analyzing by the IMR-MS, and achieving rapid and accurate measurement of the content of the volatile organic compound in the tobacco material by drawing a standard curve and by calculation. By the method, relatively-simple clean mass spectrum can be obtained, the qualitative and quantitative analysis of the volatile organic compoundis simplified, 19 types of volatile organic compound common in the tobacco material can be simultaneously, accurately and quantitatively detected, the advantage of rapid analysis is beneficial for achieving detection of a large amount of volatile samples, and the rapid analysis demand of a laboratory is satisfied.

Description

technical field [0001] The invention belongs to the technical field of compound mass spectrometry analysis, and in particular relates to a method for measuring the content of volatile organic compounds in smoking materials by using ion molecule reaction mass spectrometry technology. Background technique [0002] Tobacco materials refer to all kinds of raw materials used in the process of cigarette processing or packaging other than shredded tobacco, mainly including cigarette paper, tobacco tow, filter rods, packaging materials, adhesives, filter rod plasticizers, tobacco Additives, etc., are indispensable means of production in modern cigarette production. They play an important role in the process of developing new products, adjusting product structure, reducing tar 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 taste of cigarette...
