Enhanced Sensitivity for Biomarker Characterization in Petroleum Using Triple Quadrupole GC/MS and Backflushing
نویسنده
چکیده
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.

Sensitive Detection of Pyrethroids in Surface Water and Sediment
A method has been developed on the Agilent 7000 series Triple Quadrupole GC/MS using NCI GC/MS/MS with backflushing. It delivers estimated method detection limits (EMDLs) for pyrethroids as low as 0.05 parts per trillion (ppt) in water samples and 0.02 parts per billion (ppb) for sediment, enabling efficient monitoring of water sources for toxic pyrethroid levels.
متن کاملDetermination of Nitro-Polycyclic Aromatic Hydrocarbons in Air Particulates Using the Agilent 7000A Triple Quadrupole GC/MS System
The analysis of nitro-polycyclic aromatic hydrocarbons (nitro-PAHs) in air particulates was performed by capillary GC in combination with the Agilent 7000A Triple Quadrupole GC/MS system (G7010AA) operated in multiple reaction monitoring (MRM) mode. While classical methods for the analysis of nitro-PAHs are based on GC/MS analysis by a single quadrupole in the selected ion monitoring (SIM) mode...
متن کاملOptimizing Detection of Steroids in Wastewaters Using the Agilent 6490 Triple Quadrupole LC/MS System with iFunnel Technology
Taking full advantage of the enhanced sensitivity of the Agilent 6490 Triple Quadrupole LC/MS System requires optimization of method parameters derived on other Triple Quadrupole platforms. Optimization of steroid analysis methods in the complex matrix of wastewater results in sensitivity as low as sub-1 ng/L (1 part per trillion).
متن کاملLongterm Detection of Anabolic Steroid Metabolites in Urine
A method for the longterm detection of anabolic steroid metabolites in urine was developed using both the Agilent 6890N network GC system with an Agilent 5975B Series GC/MSD and the Agilent 7000 Series Triple Quadrupole GC/MS. Monitoring the sulfate conjugates of these metabolites, instead of the routine glucuronide metabolites allowed detection of methenolone for a post-administration period t...
