The Isotope and Organic Geochemistry Laboratory supports a range of research activities which contribute to improved understanding of Australia's petroleum resources. The research results are recorded in various databases and published in specialist reports. When applied by government agencies and exploration companies the results aid risk assessment and promotes exploratory investment; particularly in Australia's offshore jurisdiction. The laboratory also contributes to research in: marine environmental geoscience; investigating the extent of human impact on the coastal zone; carbon capture and storage and development of techniques in isotopic and organic geochemistry.
The Isotope and Organic Geochemistry Laboratory is equipped with a range of modern analytical instruments, including:
Agilent Mass Spectrometer 5975C MSD interfaced to a gas chromatograph GC 7890A
This new model GC/MS instrument is used to analyse the organic compounds occurring in the crude oils and sediments and other samples. Enhanced sensitivity and capability of simultaneously scanning in full-scan and SIR modes enables to identify and quantify organic compounds more efficiently, especially low concentration biomarker compounds.
Agilent Mass Spectrometer 5973 MSD interfaced to a gas chromatograph GC 6890
A GC/MS can be performed in either fullscan or SIR modes to identify the organic compounds occurring in the crude oils and sediments and other samples.
Agilent gas chromatograph GC 6890 (gas only)
This GC is equipped with FID and TCD and designed for gas composition analysis.
2 x Agilent gas chromatograph GC 6890N
These two GC's are used for compositional analysis of organic liquid samples. One is for various fractions, including saturates and aromatics. Another is used for whole oil samples, which can be without laboratory treatment.
Agilent 7890A Gas Chromatograph for gas analysis This is newly purchased instrument equipped with methaniser-Flame Ionization Detector, which converts CO2 (and CO) to CH4 and hence increase in sensitivity by 100-fold. It is also equipped with Thermal Conductivity Detector (TCD), a universal detector for major components, and Electron Capture Detector (ECD) with 1000-fold increase over current detection methods.
Hewlett Packard HP 6890 gas chromatograph
This GC is for general use for organic liquid samples analysis.
Thermo MAT 253 isotope ratio mass spectrometer
This isotopic analytical system is equipped with Dual Inlet system, two Trace GC/Combustion furnaces and a Flash EA (1112 Series). This instrument is currently used for GCIRMS carbon isotopic analysis for natural gases, and crude oils. A lot of organic carbon and nitrogen isotopic (and content) data have also been produced on the crude oils (fractions), kerogen, and marine and coastal sediments.
Thermo Delta V Advantage isotope ratio mass spectrometer system
This isotopic analytical system is equipped with two Trace GC/High Temperature Conversion furnaces and a TC/EA. This instrument is currently used for IRMS hydrogen isotopic analysis of natural gases, crude oils, kerogen, marine and coastal sediments.
Thermo Dionex ASE 350 Accelerated Solvent Extractor
ASE 350 is a fast extraction system for soluble organic matter from powdered rock samples.
Vinci Technology Rock Eval 6
The laboratory has two sets of Vinci Technology Rock-Eval 6 instrument which are used for the analysis of kinetics, total organic content (TOC), oil generation and potential, maturity of source rocks.
