The Thermo MAT 253 isotope ratio mass spectrometer (IRMS) with Kiel IV carbonate preparation device is based at lower campus and measures the stable isotopes of carbon and oxygen from inorganic carbonates.
The instrument contributes to a wide range of iso-geochemical fields, including paleo-climate reconstruction, palaeontology, marine forensic biology and minerology. Materials that are routinely analysed include speleothem calcite, limestone, marble, dolomitic limestone, sedimentary carbonates, bone apatite, and coral. All samples are analysed using two primary NBS standards and a secondary standard.
