GC法在物证检验中的应用

近年来,随着物证技术仪器检测方法的研究不断深入,很多新技术手段应用到案件的破获以及司法鉴定当中,为结论的准确性提供了重要保证。笔者对气相色谱法在物证检验及文件物证中的应用进行了简要的总结阐述。GC技术以其分离高效、分离速度快而准确的特性得到广泛应用。在微量物证中广泛的应用于爆炸残留物、涂料、塑料、橡胶、油类和纤维的检验,在文件形成时间上的研究中也将起到重要作用。

On the Application of GC Method in Material Evidence Examination

In recent years, along with the intensive study on the detection method of evidence technical instrument, many new techniques are applied to cracking a criminal case and judicial identification in order to guarantee accuracy of conclusion. The application of gas chromatography in material evidence examination and document evidence is briefly summarized in this paper. GC technology is widely used for its efficient, fast and accurate separation. GC technology has extensively applied to trace evidence examination such as explosive residues, coatings, plastics, rubber, oil and fiber, and will play an important role in examining the formation time of documents.
