Analysis of Polycyclic Aromatic
Hydrocarbon Derivatives by On-Line Coupled Packed-Capillary High-Performance
Liquid Chromatography–High-Temperature Gas Chromatography
Tao Jiang and Yafeng Guan
A packed-capillary high-performance liquid chromatograph (µ-HPLC) is
coupled on-line to a high-temperature capillary gas chromatograph (HTGC) through
a multiloop, nonsplit, in-column interface. Polycyclic aromatics and aliphatics
of oils of residuum and extracts of residue in the petrochemical industry are
analyzed using µ-HPLC–HTGC. Quantitative results are obtained and
discussed with respect to frame structure and carbon number distribution.
