| titleOfInvention | A kind of quality identification method of cigarette feed liquid |
| abstract | The invention relates to the technical field of quality control of cigarette feed liquid, in particular to a quality identification method of cigarette feed liquid. The method includes: mixing and shaking a cigarette feed liquid and an extraction solvent, and then performing ultrasonic extraction; taking the supernatant for purification, performing high-performance liquid chromatography analysis, and collecting the chromatographic fingerprints of test samples and standard samples; The chromatogram is processed by the original data information, and the chromatographic peaks are divided into two types: large peaks and small peaks, the relative percentage deviation of the large peak of the test sample and the standard sample is calculated, and the cosine value of the angle between the small peak of the test sample and the standard sample is calculated; according to the obtained large peak The deviation value, the cosine value of the included angle of the small peak and the tolerance control standard are used to judge the compliance of the test sample. This method can accurately identify the winning bid sample with the closest quality to the standard sample among the bid samples, and whether the quality is stable between batches. |
