TLC/FID法测定重油烃族组成方法研究

Investigation of the Analytical Method for the Heavy oil Hydrocarbon Group-Components by TLC/FID

本文研究了以EC法为基准的重油烃族组成 (即饱和烃、芳烃、胶质 ) ,TLC/FID测定方法。提出了以实际样品EC法分析结果为基础 ,测定TLC/FID定量校正因子的方法。结果表明 ,对同一类油 ,应用这一方法得到的TLC/FID的烃组成测定结果与EC法的结果相差小于 3%。

The paper introduces the analytical method for the heavy oil hydrocarbon group_components. TLC/FID technique is used and a new quantitative correcting method is suggested, in which, both developing losing and detecting difference of the sample components are considered. The analytical results of the practical sample, measured by EC(eluting chromatograph), are used as the standard values to correct those obtained from the TLC/FID. The applications show that the method has a good accuracy and is easily applied in practical analyses. For same type of the samples, the difference of the analytical results between the method introduced here and EC is small than 3%.
