Organic Geochemistry facilities

Organic Geochemistry facilities

Laboratory and Instruments

After starting at Macquarie University in 2006, Professor Simon George helped design and build a brand new organic geochemical laboratory. This lab was commissioned in June 2007. It is in rooms 340 and 344, Level 3 of building E7B, and is divided into a wet chemistry lab with four fume cupboards and an instrument lab (total floor space 72m2). It is adjacent to the 2nd and 3rd year chemistry teaching labs.

The ancillary equipment in the lab include Binder drying ovens, solvent bins, lab fridge and freezers, a high temperature furnace, wash-up facilities, analytical 5 figure balance (AND), and facilities for heating, cleaning and separation of oils and rocks extracts.

Major instrumentation includes:

  1. Accelerated Solvent Extractor (ASE300) for solvent extraction of sediments, rocks, biological samples and environmental samples.
  2. Benchtop gas chromatograph-mass spectrometer (GC-MS): Agilent GC (6890N) coupled to an Agilent Mass Selective Detector (5975B). Programmable Temperature Vaporization (PTV) inlet and flame ionisation detector. This is one of the work-horse instruments of the laboratory and is used for a wide variety of projects.
  3. Agilent purge and trap GC-MS inlet, interfaced to the Agilent benchtop GC-MS, for analysis of hydrocarbons dissolved in water-phase compounds.
  4. Pegasus 4D GCxGC-MS system, with Agilent 6890N GC, split-splitless injector and flame ionisation detector.
  5. Beuhler Isomet 4000 linear precision rock saw for fine cuts and slice experiments on rocks.
  6. Hermle centrifuge.
  7. Julabo chiller interfaced to a Buchii R-210 rotary evaporator.
  8. Millipore Direct-Q UV system for production of ultrapure water.
  9. Liquid chromatography-MS system installed in 2014, composed of a 1260 Infinity LC and fraction collector interfaced to a 6120 Quadrupole MS.
  10. Multifunction orbital shaker, Benchmark bench mixer and low temperature incubator for Australian Antarctic Division projects.

The facilities in the organic geochemistry laboratory were purchased from an ARC Lief grant, Australian Antarctic Division projects, and several Macquarie University RIBG grants, as well as initially from a generous start-up package awarded to Professor Simon George.

This lab is a shared facility at Macquarie University, dedicated to trace hydrocarbon analysis. Collaborators at Macquarie University include the Palaeobiology group in Biological Sciences, the Department of Environment and Geography, and the Department of Chemistry & Biomolecular Sciences. We have many collaborators in other groups in Australia and elsewhere.

Equipment available to my the group at CSIRO

Through agreement with CSIRO, Simon George and his group continue to work in the nearby CSIRO Earth Science and Resource Engineering laboratory on Delhi Rd, North Ryde, and collaborate with the scientists there. This has excellent wet chemistry and instrumental facilities. New equipment purchased at Macquarie University was designed to be complementary to that already available at CSIRO.
