Instrument capabilities and specification

Our facility houses three gas source isotope ratio mass spectrometers (IRMS) with various interfaces.

These systems are ideally suited for the rapid analysis of sub-milligram sized carbonate samples to ascertain their stable oxygen and carbon isotopic compositions. Additionally the linkage of IRMS to elemental analysers, allows the direct analysis of the carbon and nitrogen isotopic composition of organic matter. We also have a bespoke build greenhouse gas device which allows us the analysis low concentration of Nitrous oxide obtained offline from waters via the denitrifier method.

Stable Isotope Ratio Mass Spectrometers

  • A Thermo Delta plus Advantage interfaced with a Kiel Carbonate III preparation system. This system will run samples as small as 30 mircograms in size.
  • A Thermo Delta V interfaced with a gas bench and NA2500 for C:N analysis linked via a ConFlow III to the IRMS.
  • An elementar precisION interfaced with an Elemental Analyser, a bespoke build Green house gas device for Nitrous oxide analysis, and isoflow for Carbonate analysis for samples below 150 micrograms.
