拉曼光谱学正在成为法医学中一种重要的工具。它是一种非侵入性、非破坏性的分析方法，允许在没有任何准备的情况下检查样品。本文演示了使用该技术作为中性笔墨水分析的通用工具。为此，收集了本研究时世界市场上可获得的代表中性笔的不同品牌和型号的55种蓝色中性笔墨水。在甲醇中的初步溶解度测试允许将它们分为两类：19种染料基凝胶油墨和36种颜料基凝胶油墨。后者通过使用两种波长激光源（514.5和830 nm）的拉曼光谱（RS）进行分析。鉴定出两种主要颜料，颜料蓝15和颜料紫23。(c)2004爱思唯尔爱尔兰有限公司保留所有权利。
Raman spectroscopy is becoming a tool of major importance in forensic science. It is a non-invasive, non-destructive analytical method allowing samples to be examined without any preparation. This paper demonstrates the use of the technique as a general tool for gel pen inks analysis. For this purpose, 55 blue gel pen inks, of different brands and models representative of gel pen available on the world market at the time of this Study, were collected. A preliminary solubility test in methanol allowed separating them into two classes: 19 dye-based and 36 pigment-based gel inks. The latter were analysed by Raman spectroscopy (RS) using two wavelength laser sources (514.5 and 830 nm). Two main pigments were identified, pigment blue 15 and pigment violet 23.
