Small Research Facility, Grant Building.
The facility supports in-house research, as well as academic and commercial services in palaeoceanography, palaeoclimate, environmental and archaeological research. The Wolfson Laboratory specialises in the stable isotope mass spectrometric analysis of skeletal carbonates (including annually-banded corals and clam shells, foraminifera, and ostracods), deep-sea sediments, and waters. The facility houses three Stable Isotope Ratio Mass Spectrometers (SIRMS). A dual inlet mass spectrometer interfaced with a Kiel carbonate device is used to measure 18O/16O and 13C/12C on carbonates. A continuous flow mass spectrometer is interfaced with an Elemental Analyser, allowing the analysis of 15N/14N and 13C/12C whilst simultaneously quantifying C % and N %. When interfaced with a GasBench II the continuous flow mass spectrometer is used to measure Nitrates to obtain 15N/14N and 18O/16O. The third mass spectrometer is the elementar isoprime precisION continuous flow mass spectrometer, which is interfaced with a greenhouse gas device, an isoflow and the pyro cube elemental analyser. The greenhouse gas device, a bespoke design, can measure normal and low concentrations of Nitrates to obtain 15N/14N and 18O/16O. The isoflow interface enables carbonate and bulk carbonate analysis for 18O/16O and 13C/12C. The Vario pyro cube elemental analyser interface allows the analysis of 15N/14N and 13C/12C whilst analysing simultaneously C % and N % on this advanced mass spectrometer.
