[0035]Cigarette filter popping beads are a kind of circular capsule with fragrance added to the filter rod for cigarettes, which can release fragrance when subjected to a certain external force. In order to detect the solvent residue in the popping beads of cigarette filters, it is first necessary to break the wall of the popping beads. The experimental results show that the wall material of cigarette filter popping beads cannot be dissolved by common organic solvents. If the wall is broken by means of ultrasound and vibration for a long time, it will easily cause the loss of volatile target analytes. If only the popping beads are soaked It is not conducive to the complete dissolution of the solvent residue in the explosive beads if the sample is loaded for analysis after breaking. Therefore, it is a better sample pretreatment method to crush the explosive beads in a short time by external force. In order to avoid the loss caused by the residue of the explosive beads in the co...

[0038] According to the configuration standard working solution method that the inventive method recommends, then according to the instrument condition of the inventive method, get 5 grade series standard working solutions and carry out HS-GC / MS analysis, with the response peak area ratio of solvent residual concentration and solvent residual and internal standard Draw standard curve and standard working curve regression equation (see Figure 4 , 5 ). The limit of detection (LOD) was calculated at 3 times the signal-to-noise ratio (S / N = 3), and the limit of quantification (LOQ) was calculated at 10 times the signal-to-noise ratio (S / N = 10), while considering the possibility of recovery results Acceptability, detection limit and limit of quantitation of the final obtained method are shown in Table 2.

[0041] Using typical detection samples (such as Image 6 ), the recovery and precision experiments were carried out with the 3-level standard addition method, and the determination was repeated 5 times for each standard addition level. The recovery and repeatability results of the detection method are shown in Table 3. It can be seen from Table 3 that the recovery rate and repeatability data are ideal, the recovery rates of the three spiked levels are between 79.1-112.0%, and the relative standard deviation (RSD) is 0.5-14.9%, which can meet the needs of quantitative analysis.
