Abstract: Chemometrics have been widely applied for data processing and analysis in the field of forensic science, especially for the physical and chemical examination of physical evidence. To understand the research progress of its application in the identification of accelerant, the representative relevant domestic and foreign research in recent years was reviewed. The application of chemometrics in the evaluation of qualitative, classification, and physical evidence validity in the identification of accelerants were summarized, including the elimination of interference, the differentiation of brands and categories of accelerants, and the calculation of likelihood ratios in the identification of accelerants, and its application prospect was prospected (49 ref. cited).
