Abstract:Summary Using packed column supercritical fluid chromatography on-line with capillary gas chromatography, gasolines have been characterized with respect to the separation of hydrocarbon classes as a group as well as a detailed fingerprinting of individual components within the classes. Using selective heartcutting, specific gasoline peaks were transferred to the capillary gas chromatograph as they eluted from the supercritical fluid chromatograph. Quantitative information was collected simultaneously from the flame ionization detectors that were used on both chromatographs. This report will describe the operational chromatographic conditions that were used for gasoline separations as well as provide results of quantitative heartcut reproducibility experiments of gasolines and hydrocarbon standards.
