Analysis of Sulfur-Rich Crude Oil and Bitumen by FTMS
3 October 2011
In this application note ultra-high resolution mass spectrometry was used to characterize high mass sulfur containing compounds in crude oil and bitumen. These compounds were not accessible by GC due to their low volatility. The relative abundances of the compound classes S1, S2 and S3 in crude oil and bitumen were measured. DBE vs. carbon number plots were used to analyze the relative ratios of specific core structures like benzo- or dibenzo thiophenes of these compound classes.
