Enhanced Sensitivity for Biomarker Characterization in Petroleum Using Triple Quadrupole GC/MS and Backflushing
Abstract:
A rapid, reliable method for the routine detection and quantification of biomarkers in petroleum was developed using the Agilent 7890A/7000A Series Triple Quadrupole GC/MS with backflushing using a Pressure Controlled Tee configuration. In a single run, diverse biomarkers from several transitions can be detected, confirmed and quantified at levels as low as 2 ppm, with RSDs well below 5%. This method is suitable for “fingerprinting” of petroleum samples and the deconvolution of oil mixtures in complex, multisource petroleum systems.
