Popis: | Petroleum emulsion interfacial material (species that reside in the water/oil interface) are believed to be responsible for stabilizing emulsions in petroleum; therefore, their characterization can help to develop strategies to mitigate/manipulate petroleum emulsions. Fourier transform ion cyclotron resonance mass spectrometry (FT-ICR MS) has shown that the species present at the oil/water interface are enriched in sulfur- and oxygen-containing functionalities. However, structural and isomeric information about the chemical functionalities is still uncertain. Here, we demonstrate the potential of ion mobility mass spectrometry (IM-MS) combined with post-ion mobility collision-induced dissociation (post-IM CID) to characterize functional isomers in petroleum emulsion interfacial material. Interfacial material was isolated from Athabasca bitumen and a heavy crude oil by the wet silica method. IM time-of-flight (TOF) MS analysis shows the presence of multiple isomeric O3S1 species in both samples. Post-IM CI... |
