Abstract

Simple mineral acid extraction and open column chromatographic methods commonly used to isolate pyridinic nitrogen fractions from crude oil and rock extract appear to yield severely altered distributions of alkylquinolines and benzoquinolines. This potential analytical bias, if not recognized, could lead to incorrect geochemical interpretations. Crown Copyright © 2001 Published by Elsevier Science Ltd.
