柴油烃类组成的快速测定

Quickly Determining Hydrocarbon Types of Diesel

介绍一种快速测定柴油烃类组成的方法。以数学方法代替柴油的预分离把未分离柴油的质谱图剥离成饱和烃和芳烃谱图 ,实现采用低分辨、高电压质谱法直接测定柴油烃类组成 ,简化了分析过程 ,提高了分析效率。

A new mass spectrometric method for determining hydrocarbon types in diesel was developed. Pattern-fitting and base-line techniques to resolve the mass spectrum into saturates and aromatics spectra permit direct analysis of diesel without need for a physical separation.
