Abstract
FT-ICR MS analysis of crude oil achieves sufficient mass resolving power and high mass accuracy to allow for the baseline resolution and elemental composition assignment of thousands of heteroatomic species in a single crude oil. Electrospray ionization was limited to polar species that are readily protonated or deprotonated. Two other ionization methods (FD and APPI) were coupled to probe the much larger fraction of nonpolars (e.g., aromatic hydrocarbons and thiophenes), illustrated for the aromatic fraction of a heavy crude. FD produced even-electron ions, while APPI produced even- and odd-electron ions. This is an abstract of a paper presented at the 229th ACS National Meeting (San Diego, CA 3/13-17/2005).
