“…GC–EI-MS is also widely used to analyze volatile petroleum hydrocarbons (alkanes, cyclanes, isoprenanes) and relatively low-molecular-weight hetero-organic compounds separated by GC. This type of research includes, for example, popular determinations of sterane and triterpane petroleum biomarkers [ 141 ] and adamantanoid structures [ 142 ].…”

This review is devoted to the consideration of mass spectrometric platforms as applied to omics sciences. The most significant attention is paid to omics related to life sciences (genomics, proteomics, meta-bolomics, lipidomics, glycomics, plantomics, etc.). Mass spectrometric approaches to solving the problems of petroleomics, polymeromics, foodomics, humeomics, and exosomics, related to inorganic sciences, are also discussed. The review comparatively presents the advantages of various principles of separation and mass spectral techniques, complementary derivatization, used to obtain large arrays of various structural and quantitative information in the mentioned omics sciences.

“…For example, gas condensates from the Mary Ann and Gulf of Mexico 823 fields contain more than 60 ada mantanes and higher diamondoids ranging from ada mantane and alkyladamantanes to trimantane and tet ramantane derivatives [1]. Tri and tetramantanes were also identified in domestic crude oils [2].…”

The structure of perhydrofluorene and its isomerization products 1,3,5 trimethyladamantane, 1,3,6 trimethyladamantane, cis 1,3,4 trimethyladamantane, trans 1,3,4 trimethyladamantane, 1 ethyl 3 methyladamantane, cis 1 ethyl 4 methyladamantane, trans 1 ethyl 4 methyladamantane, 1,2,6 trimethy ladamantane, and 1,2,8 trimethyladamantane of the general formula C 13 H 22 has been studied using the Becke-Lee-Yang-Parr (B3LYP) hybrid energy functional of electron density with the 6 31G* basis set. The geometric and electronic characteristics of the compounds and their total energy, transformation energies, entropies of transformations, and normal vibration frequencies have been calculated. It has been shown that the calculated Gibb free energies of formation for the perhydrofluorene isomerization products are in quali tative agreement with the experimental product composition of the isomerate.

The composition and physical properties of spilled oil have great changes during the seriously weathering process. It brings great difficulties to the source identification of oil spill. So the stable and trustworthy diagnostic ratios (DRs) for accurate identification of severely weathered spilled oils are very important. The explosion of Sinopec pipeline happened on November 22, 2013 at Qingdao, China. Local beaches at Jiaozhou Bay were polluted by spilled oils. We have collected original spilled oil samples from an area free from human interference near the oil leakage point after the accident. Synchronized with actual beach weathering, laboratory experiments were conducted to simulate oil weathering for 360 days by using the collected original spilled oil samples. Based on t test and the repeatability limit method, 50 diagnostic ratios (DRs) of adamantanes were screened. Four DRs, namely 1,3-dimethyladamantane/total dimethyladamantane, 1-methyladamantane/(1-methyladamantane + 1,3-dimethyladamantane), dialkyl diamantane/total diamantane, and diamantane/(diamantane + dialkyl diamantane), have maintained remarkable stability during the simulated weathering experiments and field weathering process. These stable ratios can retain the characteristics of oil source during weathering. They are very beneficial to improve the accuracy of identifying the source of severely weathered oil and can be used as an effective supplement to existing index system for source identification.
