    Abstract

    This study establishes a quick way to test lipsticks. Twenty-eight lipstick samples were classified using Raman and X-ray fluorescence spectroscopy. Using Raman spectroscopy technology to analyze and test samples, the samples can be effectively classified according to the difference in Raman characteristic peaks. A principal component analysis was used to process the data. The classification based on Raman characteristic peaks was scientifically validated when combined with Pearson correlation analysis. When combined with X-ray fluorescence spectroscopy, two types of groups were obtained, and the groups were distinguished based on Ca-Ti. The result shows that this method is simple and fast to operate and does not require special pretreatment. This study will provide a new idea for public security organs to investigate and solve cases and has broad application prospects in public security practice.
