在法庭化学中,用高灵敏度仪器分析方法研究微量物证具有不可代替的作用。通过仪器分析不仅能够确定微量物证的组成 组分和结构,而且还能借助有效成分更精细地刻画其形成及变化规律 推断其来源,确定微量物证与案件的关系。色谱、色质联用、毛细管电泳和分子光谱法对毒物、毒品、炸药和染料等有机类物证及物证中有机成分的分析 充分显示了这些分析技术在鉴定微量物证中的优势。
In forensic chemistry, the use of high-sensitivity instrumental analysis of trace evidence has an irreplaceable role. Instrument analysis can not only determine the composition and structure of the trace evidence, but also make it possible to deduce the origin and determine the relationship between the trace evidence and the case by means of more precise description of the formation and variation of active ingredients. Chromatography, Chromatography, Chromatography, Capillary Electrophoresis and Molecular Spectroscopy Analysis of organic components in organic evidence and evidence of poisons, drugs, explosives and dyes fully demonstrates the advantages of these analytical techniques in the identification of trace evidence.
