摘要:

在法庭科学领域,油墨是微量物证分析的关键要素,对案件的侦破具有重要作用。 色料是油墨的主要组成之一,具有独特的种类与含量,且会随时间降解,是判鉴文件形成时间和真伪的重要依据。 本文对文件图文油墨的色料成分进行了分类与概述,介绍了用于油墨色料成分鉴定的多种光谱、色谱与质谱分析技术及其优势与局限性,重点讨论了拉曼光谱法、原位质谱法等无损检验方法,以及化学计量学与传统分析方法的结合,并基于此对法庭科学文件色痕检验未来研究重点与前景进行了展望,以期为法庭科学文件检验工作者提供参考和借鉴。

Abstract:

In the field of forensic science, ink is a key element in the analysis of trace physical evidence and plays an important role in the detection of cases. Colorants is one of the main components of the ink, has a unique type and content, and will be degraded over time, is an important basis for identifying the time of formation and authenticity of the document. This paper classifies and summarizes the colorants of the document graphic ink, introduces a variety of spectroscopy, chromatography and mass spectrometry techniques used for the identification of ink colorants and their advantages and limitations, focusing on Raman spectroscopy, ambient ionization mass spectrometry and other non-destructive testing methods, as well as chemometrics and the combination of traditional analytical methods, and based on the future focus of the forensic scientific documents and prospects for the colorants test prospects, in order to provide reference for forensic scientific document examination workers.

Key words: Colorants, Formation time, Spectroscopy, Chromatography, Ambient ionization mass spectrometry, Chemometrics
