摘要
以碳酸钙为主要成分配制了用于显现潜在手印的新型小颗粒试剂,研究了手印遗留时间、手印水浸时间、不同浸泡成分等外界条件对碳酸钙小颗粒试剂显现效果的影响,并与同类其它小颗粒试剂进行了对比试验,结果表明,碳酸钙小颗粒试剂对于水浸以及常见饮料浸湿的潜在手印具有良好显现效果,为潜在物证的提取提供了一种新方法。
Calcium carbonate small particle reagent for the detection of latent fingerprints was prepared. The influences of fingerprint age, dipped time, dipping materials, etc. to the detection of fingerprints were studied. The comparison of development of fingerprints by calcium carbonate small particle reagent and other type of small particle reagents was test. The result shows that Calcium carbonate small particle reagent is good at developing wet fingerprints, as well as beverage rinsed fingerprints. It is a new method for the detection of latent evidence.
