In order to perform detailed studies on the source, transport, and ultimate fate of acute and chronic releases of petroleum hydrocarbons high-resolution separations of target compounds and compound classes from complex mixtures such as petroleum frequently require techniques with high resolving power such as comprehensive two-dimensional gas chromatography (GC×GC). GC×GC coupled with flame ionization (FID), time of flight mass spectrometry (TOF-MS), and high resolution time of flight mass spectrometry (HRT-MS) are three of the high resolution tools employed in our laboratory. Here we examine a number of oil spills (Ixtoc I, Exxon Valdez, Cosco Busan, Deepwater Horizon, and Refugio) using traditional and un-traditional oil spill forensic compounds in order to gain a more complete understanding of (a) which compounds persist in the environment and (b) how we can use high resolution techniques to forensically identify specific petroleum sources.
