摘　　要：环境污染损害鉴定案件中涉及的污染物种类繁多,往往会出现一些常规分析手段无法鉴定的污染物。本文利用全二维气质联用仪对标准柴油和机油样品进行分析,并利用样品中特征有机物种类、含量以及小于C25的化合物所占比例这一特征对“土炼油”案件中常见的各种油类物质进行实践研究。这对于明确鉴定样品种类具有重要的指导意义。该方法可为下一步按照相应的国家标准对待鉴定油品含水量、黏度、酸值和机械杂质等指标进行测定提供依据。Identification of environmental pollution damage is highly professional,which involves a wide range of pollutants,and some of them are often difficult to be identified by conventional analysis methods.In this paper,a full two-dimensional gas chromatography-mass spectrometer is used to analyze standard diesel and oil samples,and the characteristics of the types and content of organic compounds in the samples and the proportion of compounds smaller than C25 are used to conduct practical research on various oily substances commonly found in“refining oil”cases.This has important guiding significance for clearly identifying sample types.This method can provide a basis for the next step to determine the water content,viscosity,acid value and mechanical impurities of the identified oil according to the corresponding national standards.
