%X On-line coupling of capillary liquid chromatography-capillary gas chromatography (CGC) technique for detailed group component analysis of aviation kerosene, diesel fuels, lubricating oils, extraction oils, and residuum, is described. Aromatics in fuel oils were separated according to their ring number and structures. Different eluents were stored in loops on interface, and introduced sequentially onto the CGC for detailed separation and quantitative analysis. Capillary column switching-back flushing with a single detector was developed for the analysis of aromatics in gasoline and aviation kerosene. The early eluting components from a pre-column and the components of interest (aromatics plus heavier compounds) eluting from an analytical column were all directed to the same flame ionization detector, which performed quantitative analysis of aromatic hydrocarbons in oils by correction factor normalization method. Real oil samples were analyzed and the results showed that the reproducibility, accuracy and reliability of the method can fulfill the requirements of practical application.
