Until now, researchers have measured stable carbon isotope ratio between 12C and 13C by converting material to CO2. However, it has a limitation that molecular level Stable carbon isotope ratio can’t be obtained. In this study, ultra high resolution mass spectrometry has been evaluated whether it can be used to obtain Stable carbon isotope data at the molecular level. Crude Oils obtained from different locations were analyzed by use of APPI FT-ICR MS for Crude oil analysis. The obtained data were compared to those from Elemental Analysis-Isotope Ratio Mass Spectrometry (EA-IRMS).
