紫外光谱法分析车用润滑油

Analyzing Automotive Lubricants by UVS

在道路交通事故中经常会遇到油脂物证的检验,因此建立一种简便、灵敏、准确的鉴定油脂物证的鉴别方法是十分必要的。文章对64种不同品牌及相同品牌不同型号的市售车用润滑油样品进行了紫外光谱分析,依据吸收峰的个数及位置不同,可将其分为14大类,同时还实现了模拟现场中沥青和水泥路面上的润滑油与原样品的种类识别。实验结果表明:用该法鉴别车用润滑油是一种简便、快速、灵敏、准确的方法。

It＇s very necessary to establish a simple,sensitive,accurate identification method of oil material evidence because the examinations of oil materials are often encountered in road traffic accidents.Through conducting ultraviolet spectrum analysis to 64 kinds of automotive lubricant samples,which are of different brands and same brands with different types for sale,this article classifies them into 14 categories by the number and different locations of absorption peaks and achieves the goal of identifying the kinds of lubricants and original samples on the asphalt and cement road in the simulated scenes.The experimental results show that it＇s a simple,rapid,sensitive and accurate method to identify automotive lubricants by using UV spectrometry.
