Quantification of Polycyclic Aromatic Hydrocarbons in Marine Environmental Samples
The potential for use of perdeuterated polycyclic aromatic hydrocarbons (PAHs) in the analysis of marine sediments and organisms by a method that employs a gas chromatography/mass spectrometer (GC/MS) system operating in the multiple ion monitoring (MIM) mode is examined. Questions concerning chemisorption of PAHs on adsorbents, hydrogen-deuterium exchange, interfering compounds, and the separation of deuterated and protiated PAHs by gas or liquid chromatography are considered and experiments that were performed to obtain answers are described. The evidence indicates that deuterium labelled PAHs are useful carriers and internal standards for their unlabelled forms in the analysis of marine organism and sediment samples.
