Abstract

A method is described for the isolation, characterization and fingerprinting of porphyrin mixtures from geological samples. The procedure, which employs various modern analytical techniques (e.g.· high performance liquid chromatography , computerized mass spectrometry and uv/vis spectrophotometry), is simple, fast and should, thus, facilitate studies concerned with the structure elucidation of these pigments. Applied to a wide variety of oil and shale samples from the Arabian Gulf, Europe , North America , Venezuela and Indonesia, this method of crude oil fingerprinting provides a new technique for oil classification and recognition, and should prove useful in the twin areas of oil exploration and oil pollution control.
