茜素红S(ARS)是组织学鉴定钙沉积物的一种常用有机染料,它能同底火残留物中存在的钡、铅等金属离子形成有色产物,并能识别不同厂家生产的底火残留物成份,用常规的组织学技术就能完成。 在美国每年因火器伤致死的多达3万人以上,多数因自杀和他杀,所有的自杀和他杀均为近距离射击,确定射击残留物是法医学研究的重要线索。许多技术对于这项工作是成功有效的,如:中子活化分 Alizarin Red S (ARS) is a commonly used organic dye for the histological identification of calcium deposits. It can form colored products with the metal ions such as barium and lead present in the bottom fire residue, and can identify the bottom flame residues produced by different manufacturers Ingredients, using conventional histological techniques can be completed. In the United States, as many as 30,000 people are killed each year by firearms, most of them commit suicide and kill him. All suicides and killings are shot at close range. Determining firing residues is an important clue to forensic research. Many techniques are successful and effective for this task, such as neutron activation
