The complex chemical composition of crude oils presents many challenges for rapid chemical characterization in the case of a spill. A number of approaches are currently used to “fingerprint” petroleum‐derived samples. Gas chromatography coupled with mass spectrometry (GC‐MS) is the most common, albeit not very rapid, technique; however, with GC‐MS alone, it is difficult to resolve the complex substances in crude oils. This study examined the potential application of ion mobility spectrometry–mass spectrometry (IMS‐MS), coupled...
