Petroleum and its fractions are some of the most complex mixtures found in analytical chemistry. Mass spectrometry currently plays an increasing role in the characterization of these matrices. Since the last review on this topic in 2011, several new approaches have been introduced, and these approaches increasingly use sample fractionation by extraction and/or liquid chromatographic techniques. This review considers molecular mass spectrometry (with special emphasis on the use of ion mobility) and inorganic mass spectrometry. The combination of both techniques paves the way to “petrointeractomic” approaches, which are introduced as a novel, important part of “petroleomic” approaches.
