本文介绍了用四极质谱直接进样测定重质馏份油芳烃烃类组成的方法，分析了仪器条件对实验结果的影响。实验操作简便，数据重复性好，通过与石科院分析结果的比较及掺对实验说明该方法比较准确可靠。
This paper introduces the method of direct injection of quadrupole mass spectrometry for the determination of aromatic hydrocarbons in heavy distillate oil and analyzes the influence of instrument conditions on the experimental results. The experimental operation is simple and the data repeatability is good. The comparison with the results of the analysis by the ASTRI and the experiment on the method show that the method is more accurate and reliable.
