There are many studies on analyzing the chemical compositions of Crude Oil. Gas chromatography-Mass spectrophotometry (GC-MS) has been used to analyze light constituent of Crude Oil, but this is limited for the heavy constituents. The heavy constituents mentioned either high molecular weight, polycondensed, or polar compounds that cannot be detected by using conventional techniques. Latterly, Ultrahigh-resolution mass spectrometry (UHR-MS) is used to analyze heavy compounds. But UHR-MS technique has limitations. Ionization discrimination can limit the number of compounds observed by the technique. High-performance liquid chromatography (HPLC) ring-type separation is one of the methods to overcome limitations. The combined technique disclosed the aromaticity increased as the fraction number increased. The structures and distribution of heteroatom class compounds could be also explained using the combined technique. In addition, MS/MS spectra showed core structures of Crude Oil fractions.
