ResumoAbstract A high-performance liquid chromatographic (h.p.l.c.) separation, having selectivity for the number of fused aromatic rings up to four, was used to separate polynuclear aromatic hydrocarbon (PAH) ring classes. Two crude oils: the heavy Lloydminster and the light Medicine River oils from the Alberta Basin were analysed. Three- and four-ring structures dominated the aromatic concentrates of both oils. The abundance of five and larger fused ring contents, and higher degree of alkyl substitution distinguish the Lloydminster polyaromatic content. The analytical potential of this approach was studied using refractive index and ultraviolet detectors, gas chromatography, mass spectrometry, 13 C n.m.r. and spectrofluorometry. The procedure proved to be useful for characterization of the complex PAH mixture in hydrocarbon materials.
