英文摘要: The heavy oils from petrochemical industry were analyzed by an on-line coupled packed capillary high performance liquid chromatography (mu-HPLC) and high temperature capillary gas chromatograph (HTGC), An aminosilane silica packed mu-HPLC column separates the sample into aliphatics, one-to five-ring polycyclic aromatic hydrocarbons and resin ect,, The volume of each fraction is about 30 similar to 60 mu L, which is stored in turn in a multi-loop interface: from a single LC injection, and then transfered into GC for quantitative analysis. The content and the carbon number distribution of each chemical class are obtained. The RSD is less than 5%, Examples were given to demonstrate the applicability of the method.
