FT-ICR-MS is applied for the characterization of polar compounds like NSO (nitrogen, sulfur and oxygen containing organic compounds) in fossil and recent geological samples (sediments, sedimentary rocks, coals, soils, and water samples), assessment of secondary alteration processes in petroleum systems (maturation, biodegradation, and migration), characterization of high molecular weight aromatic compounds, elucidation of molecular formulae and molecular imaging.

GC-MS in general is used …
