摘　　要：以直馏柴油馏分、重油饱和烃馏分和重油芳烃馏分为样品 ,研究用四极杆GC/MS代替磁式质谱仪 ,等效采用ASTMD2 42 5、D2 786和D32 39方法测定石油馏分的烃类组成 ,并开发了相应的通用分析软件。研究结果表明 ,采用自动进样的四极杆GC/MS进行石油馏分烃类组成分析 ,均能满足ASTM方法的重复性和再现性要求 ,大大降低了烃类组成分析的成本 ;分析软件的应用 ,使数据处理计算机化 。Group analysis of petroleum fractions by quadrupole GC/MS equivalent to ASTM D2425, D2786 and D2329 instead of magnetic mass spectrometer was studied. Straight run diesel oil, saturated hydrocarbons of VGO and aromatics of VGO were taken as testing samples, and analysis software was developed. The said GC/MS method could meet the ASTM demands of repeatability and reproducibility, which significantly decreased the analysis cost.
