Abstract: The heavy oils from petrochemicaLINdustry were analyzed by an on-line coupled packed capillary high performance liquid chromatography(μ-HPLC) and high temperature capillary gas chromatograph(HTGC). An aminosilane silica packed μ-HPLC column separates the sample into aliphatics, one-to five-ring polycyclic aromatic hydrocarbons and resin ect.. The volume of each fraction is about 30～60 μL, which is stored in turn in a multi-loop interface from a single LCinjection, and then transfered into GCfor 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.

Key words: On-line coupled HPLC/GC, Packed capillary HPLC, High temperature capillary gas chromatography, Heavy oil
