稳定性同位素质谱技术在微量物证检验中的应用研究进展

Research Progress on the Application of Stable Isotope Mass Spectrometry in Trace Physical Evidence Analysis

摘要: 综述了稳定性同位素质谱技术，主要包括元素分析-稳定同位素比值质谱法（EA-IRMS）和气相色谱-稳定同位素比值质谱法（GC-IRMS），在法庭科学微量物证（包括助燃剂、爆炸物、油漆、土壤、纤维、胶带、塑料以及纸张等）分析中应用的研究进展，主要涉及物证的样品区分、产地溯源和同一认定等（引用文献54篇）。

Abstract: Research progress of the application of stable isotope mass spectrometry techniquesincluding elemental analysis-stable isotope ratio mass spectrometry (EA-IRMS) and gas chromatography-stable isotope ratio mass spectrometry (GC-IRMS) in the analysis of trace material evidence (i.e., combustion improver, explosive, paint, soil, fiber, tape, plastic, paper, etc.) in forensic science, was reviewed. Main applications involved the sample identification, origin traceability and identical authentication for trace material evidence (54 references cited).
