Analytical Services

The Centre is well equipped for stable isotope studies and offers a range of analytical and interpretive services to researchers both within UWA and in the broader scientific community.

We use the following instrumentation:

SerCon Elemental Analyser (Gas Solid / Liquid Preparation Unit)
SerCon Elemental Analyser
Coupled with a 20-22 Stable Isotope Ratio Mass Spectrometer (Sercon, Crewe/ UK) δ13C, δ15N, δ34S, C%, N%, S% in natural solid samples (plants, soils and animal tissues) and precipitated or extracted sulphates and sulphites (for example, from water samples).
Picarro Cavity Ring-down Spectrometer L1115-I
Picarro Cavity Ring-down Spectrometer

With ChemCorrect software δ2H and δ18O of liquid and vapour water samples.

Picarro Cavity Ring-down Spectrometer L2140i
Picarro Cavity Ring-down Spectrometer
With ChemCorrect software and microcombustion unit - high resolution  δ2H,  δ18O and δ17O of liquid and vapour water samples. 
Delta XL Isotope Ratio Mass Spectrometer (Thermo/Germany) connected with:
  • GasBench II (GB) δ13C and δ18O in carbonates, δ13C in DIC (Dissolved Inorganic Carbon), δ13C in CO2
  • Thermal Conversion /Elemental Analyser (TC/EA) δ18O in organic materials, phosphates, sulphates and nitrates.
Delta V Plus Isotope Ratio Mass Spectrometer (Thermo /Germany) connected with:
Delta V Plus Isotope Ratio Mass Spectrometer
  • Thermo Elemental Analyser Flush 1112 via Conflo IV δ13C, δ15N, C%, N%, in natural solid samples (plants, soils and animal tissues) and precipitated or extracted sugars, cellulose, nitrates and other compounds.
  • Finnigan LC-IsoLink δ13C in DOC (Dissolved Organic Carbon) in water extracts and pre-concentrated water samples.
Agilent 6890/5973B GC-MSD
Supporting molecular analysis of soil and older sedimentary organic matter, oils, aquatic natural organic matter. This system is fitted with an autosampler for high throughput of solvent extracted organics, their fractions (alipahtics/aromatics) and derivatives (polars/phospholipid fatty acids). Several analytical pyrolysis devices are also available for the characterisation of consolidated sediments, including a laser microprobe to uniquely support the separate analysis of morphologically distinct entities within these materials.
Additional major devices and equipment
Ball mills for sample grinding and homogenisation.
Freeze-dryer: Virtis Benchtop 2K.
Microbalances: Sartorius MC210S (0.01mg) Mettler Toledo X6T (0.001 mg).
Vacuum line for cryogenic extraction of water from soil and plant samples.
Equilibration method for analysis of water from soils and small biological samples.
