Embodiment 1

[0030] The screening method for volatile organic compounds in the cigarette filter quick-fried beads of the present embodiment, the process flow chart is as follows figure 1 shown, including the following steps:

[0031] 1) Take out two popping beads from the popping bead cigarette A, put them into a 20ml headspace bottle, puncture the popping beads with a disposable syringe, and let the liquid in the popping beads flow out; carry out headspace sampling of the liquid in the popping beads and Combined with comprehensive two-dimensional gas chromatography-mass spectrometry for full-scan analysis of the sample, the following results are obtained: figure 2 The full-scan profile shown;

[0032] Headspace sampling conditions are as follows: sample loop volume is 3.0ml, sample equilibrium temperature is 40°C, sample loop temperature is 160°C, transfer line temperature is 180°C, sample equilibration time is 20.0min, sample vial pressurization pressure is 138kPa, plus The pressure t...

Embodiment 2

[0042] The method for screening the volatile organic compounds in the puffed beads of the cigarette filter in this embodiment is aimed at the puffed puffs B, and the specific operation steps and process parameters are the same as those in Example 1.

[0043] The headspace-comprehensive two-dimensional gas chromatography mass spectrometry full scan diagram after optimizing the selected qualitative spots in this embodiment is as follows Figure 4 As shown, the test results are shown in Table 2.

Embodiment 3

[0048] The method for screening the volatile organic compounds in the popcorn of the cigarette filter in this embodiment is aimed at the popcorn C. The specific operation steps and process parameters are the same as those in Example 1, and the test results are shown in Table 3.

Abstract

The invention relates to a screening method of a volatile organic compound in a cigarette filter tip blasting-bead. The method comprises the steps of (1) performing headspace sampling on liquid in the blasting-bead, and combining a combined comprehensive two-dimensional gas chromatography mass spectrometry for carrying out full-scanning analysis on a sample to obtain a full-scanning spectroscopy; (2) automatically comparing chromatographic peaks of the full-scanning spectroscopy and database information through data software to obtain a preliminary qualitative result of each spot; (3) checking the preliminary qualitative result of each spot, combing a peak structure and similarity proportion, optimizing the full-scanning spectroscopy to obtain an optimal spectroscopy, and manually comparing with the database information to obtain an optimal qualitative result; (4) using percentage response for carrying out semi-quantitative analysis on the optimal qualitative result. The method has the advantages of short detection time, simplicity and convenience in operation, high sensitivity, comprehensiveness in screening, and the like, not only can be used for monitoring conventional harmful volatile organic compounds, but also can be used for monitoring if flavor components allowed to be added exceed the limitation or not so as to ensure the safety of blasting-bead products.

Description

technical field [0001] The invention belongs to the technical field of physical and chemical testing of tobacco materials, and in particular relates to a screening method for volatile organic compounds in popping beads of cigarette filters. Background technique [0002] There are more than one small capsule beads containing liquid in the filter tip of pop-pop cigarettes. Squeezing the liquid in the pop-cap capsules can increase the flavor of the cigarette during smoking, strengthen the aroma or characteristics of the cigarette, and make consumers more comfortable. Fresh experience. The popping beads must be manually pinched and popped during the smoking process of the cigarette, and the time of pinching and popping can be arranged according to preference. [0003] Volatile organic compounds refer to organic compounds with a saturated vapor pressure greater than 70Pa at normal temperature and a boiling point below 260°C at normal pressure, or organic compounds with correspon...
