摘要： 本研究应用GC-MS和IRMS技术对不同风化程度的柴油开展溯源分析。通过分析43个柴油样本中8个不同风化度样本的GC-MS正构烷烃化学指纹特征，明确了基于化学指纹进行柴油溯源的边界条件；通过柴油总碳及单烃同位素比值分析，建立了柴油同位素指纹图谱。结合化学指纹可更有效地区分不同柴油，为火灾调查提供支持。

Abstract: Source identification study on diesel fuels with varying degrees of weathering was conducted using gas chromatography-mass spectrometry (GC-MS) and isotope ratio mass spectrometry (IRMS) techniques. By analyzing the GC-MS chemical fingerprint characteristics of n-alkanes in 43 diesel samples across 8 weathering levels, the boundary conditions for diesel source identification based on chemical fingerprints were determined. Analysis of total carbon and monohydrocarbon isotope ratios in the diesel samples yielded isotopic fingerprints. Linking these isotopic fingerprints with the chemical fingerprints enables more effective differentiation between diesel fuel sources, providing support for fire investigation.

Key words: chemical fingerprint, weathering, stable isotope fingerprint, fire investigation, traceability of diesel
