title: Use of a GC/MS/MS technique in determination of biomarkers in regional petroleum.
abstract: The optimum conditions of a GC/MS/MS operation based on the covariant scan of electrostatic-magnetic fields on the trisector double focusing mass spectrometer JMS-HX100 have been searched for and procured. The distribution of C(29) sterane biomarkers in Arabian Medium crude oil is obtained by utilizing the best acquired parameter settings.
