四个重质原油，Boscan，Cerro Negro，威尔明顿，和普鲁德霍湾，已被检查的高效液相色谱结合石墨炉原子吸收检测器（HPLC/GFAA）提供钒指纹和分子量分类的钒卟啉和非卟啉化合物存在。我们还试图在这些重质原油中形成钒卟啉和非卟啉化合物，通过比较它们的尺寸排阻和极性氨基氰基分离的钒直方图真实的化合物。参考文献35篇，图8幅，表3张。
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.
