Four heavy crude petroleums, Boscan, Cerro Negro, Wilmington, and Prudhoe Bay, have been examined by high-performance liquid chromatography in combination with graphite furnace atomic absorption detection (HPLC/GFAA) to provide both a vanadium fingerprint and a molecular weight categorization of the vanadyl porphyrin and non-porphyrin compounds present. We have also attempted to speciate the vanadyl porphyrin and non-porphyrin compounds in these heavy crude oils by comparison of their size exclusion and polar aminocyano separated vanadium histograms to authentic compounds. 35 references, 8 figures, 3 tables.
