摘要
重质矿物油是案发现场常见的微量物证之一, 快速准确的区分重质矿物油种类可以为案件侦破提供方向, 缩小侦查范围。本文采用傅里叶变换红外光谱法和拉曼光谱法对69个重质矿物油样本进行了分析研究, 发现不仅不同种类的重质矿物油谱图存在差异, 相同种类不同厂家的重质矿物油谱图也有区别。研究结果表明, 联合使用红外光谱法和拉曼光谱法可以较好地对重质矿物油样本进行区分, 效果良好。
Abstract
Heavy mineral oil is one of the common trace physical evidence at the scene of the crime.The rapid and accurate identification of heavy mineral oil can provide a direction for case detection and narrow the scope of investigation.this paper analyzed 69 heavy mineral oil samples by Fourier transform infrared spectroscopy and Raman spectroscopy, finding that not only different kinds of heavy mineral oil spectra vary, even the same type of different manufacturer of heavy mineral oil spectra also have differences.The results show that the combination of infrared spectrometry and Raman spectrometry can distinguish the heavy mineral oil samples and have good results.
