When compared to the classical silica gel/alumina column chromatographic method, the neutral alumina procedure, recently validated for the isolation of organic nitrogen fractions from crude oils/rock extracts, appears to yield severely altered distributions for many classes of monoaromatic hydrocarbons in the aromatic hydrocarbon fraction. The potential analytical sequestration, if not recognized, could lead to erroneous geochemical interpretations. (C) 2000 Published by Elsevier Science Ltd. All rights reserved.
