摘要：
A two-dimensional gas-phase separation technique, ion mobility-mass spectrometry (IM-MS) is applied to the analysis of crude oils. In this approach, ions are generated by laser desorption/ionization and separated before MS analysis on the basis of collision cross-section (that is, apparent surface area of the gas-phase ion). The capacity to separate petroleum-derived molecules having the! same nominal mass in the mobility dimension is demonstrated. Inspection of IM-MS spectra reveals a high degree of diversity in structure and chemical class for crude oil components.
