On September 10, 1999, the Science and Technology Bureau of the Ministry of Public Security hosted a research appraisal meeting of “Scientific Research Achievements of Traces and Identifications” on the key project of 95 key science and technology projects of the Ministry of Public Security under the auspices of China Criminal Police College. The panel believes that this trace agent has the advantages of bright color, complete chromatogram, good light stability, high fluorescence intensity, wide excitation light spectrum, large Stokes offset, strong affinity with fingerprint lines, anti-hygroscopicity and Good flow properties, as well as a wide range of applications and other characteristics. This result is a major breakthrough in handprinting powder, which can completely replace the imported fluorescent powder, the product performance index reached the international advanced level. The product can be used ordinary powder brush brushing significant on-site fingerprints, the operation method is simple. Experts agree that the product cost-effective, practical
