• The C^sub 3^ vs SH^sub 4^ (0.0034 Da) mass split is considered to be one of the most critical mass splits in petroleomics and is relevant because of the regulatory requirements for sulfur in petroleum fractions. To date, there are two ways to resolve mass splits such as C^sub 3^ vs SH^sub 4^: (a) ultrahigh resolution Fourier transform mass spectrometry (FT-MS); (b) high-resolution chromatography such as comprehensive two-dimensional gas chromatography (GCxGC). High-resolution chromatography minimizes the mass spectral resolution required to distinguish these key chemical constituents and provides additional sample characterization via isomer separation. High resolution mass spectrometry enables unambiguous chemical formulas determination and structural elucidation. In this paper, we demonstrate the combination of high resolution GCxGC with high resolution time-of-flight mass spectrometry to distinguish the C^sub 3^ vs SH^sub 4^ mass split and other common mass splits in a crude oil sample.
