MAT253 and Kiel IV
Thermo Fisher Scientific 253 IRMS, with Kiel IV carbonate preparation device
This instrument is dedicated for δ18O, δ13C analyses of carbonates. The system has been optimized to run low mass carbonate samples, allowing us to obtain high-precision isotopic results from systems where sample size was previously considered a limiting factor. Examples include the ability to analyze individual specimens or chambers of foraminifera, generate continuous down core isotopic records in high-sedimentation rate or polar settings where carbonate is scarce, and resolve high temporal fidelity in systems such as otoliths, bivalves or sclerosponges.
