liquid chromatographic separation of sediment rock and coal

Liquid Chromatographic Separation of Sediment, Rock,

1997-10-15 · A method is described for the rapid fractionation of sediment, rock, and coal extracts and crude oils into compound classes. The method is based on combined polarity/affinity chromatography of soluble organic matter. Five heterocompound fractions are obtained in addition to the conventional saturated and aromatic hydrocarbon fractions. Model compound studies show that those fractions are ...
