This article describes the analysis of biomarkers in crude oil using the Agilent 7200 GC/Q-TOF system. With a high-resolution time-of-flight mass spectrometer, a diluted sample can be analyzed without fractionation, and the biomarkers of interest can be measured by exploiting the high selectivity of ion extraction at accurate mass. The system has excellent sensitivity, allowing for the selective detection of dibenzothiophene, alkylated dibenzothiophenes, and hopanes. Using the Agilent GC/Q-TOF system in MS/MS mode, low levels of steranes can be selectively detected.
