Abstract
High resolution glass capillary columns coated with SE 52 liquid phase were used to resolve the indigenous hydrocarbons extracted from sediment samples collected from three outer continental shelf areas. The extracts were then spiked with small amounts of aliphatic or aromatic components isolated from a Louisiana crude oil and rechromatographed. The resolution was sufficient to separate almost all the isoprenoid, branched and cyclic alkanes associated with petroleum. Additionally, many of the key petroleum aromatics could also be resolved from naturally occurring organics. Such chromatographic procedures will aid in distinguishing between indigenous hydrocarbons of contemporary origin and those known to be associated with fossil hydrocarbon pollution of marine sediments.This publication has 1 reference indexed in Scilit:
