MAT253 and Kiel IV

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.
