چکیده انگلیسی
Comprehensive two-dimensional gas chromatography coupled to time-of-flight mass spectrometry (GCÂ ÃÂ GC-TOFMS) was explored as a powerful tool to assess diamondoids in petroleum fluids. This work demonstrates the possibility to calculate diamondoid indexes, perform relative quantitations, and complete saturated biomarker assessments in one chromatographic run. Tetramantanes and triamantanes identification resulted in new discovered compounds that can be used for assessment (e.g., for new maturity indexes) depending on the position of alkyl-substitution. Methyl-protodiamantanes and alkyl-substituted diamondoids with chains bigger than ethyl were detected (except for tetramantanes) as a consequence of the improved resolution achieved by GCÂ ÃÂ GC-TOFMS. Further studies using this method may lead to improved understanding of the formation mechanisms of diamondoids and highly mature petroleum fluid compositions.
