The MAT252 (above left) is used exclusively with the Kiel III (above right) for the high-precision δ18O and δ13C analysis of pure calcium carbonate (e.g., forminifera, otoliths, speleothems, shells).
Delta Plus - Dual Inlet System
This system is primarily used with the water equilibration device to analyze δ18O of water samples at high precision. When connected with the GC it is also used for compound-specific δD analysis (e.g., δD of alkenones). Clockwise (from top left): DeltaPlus with Dual Inlet, GC-H, Water equilibration, TCEA (for liquids).
Delta Plus System
DeltaV - Gas Bench System
The DeltaV – GasBench system is used to analyze the δ13C of CO2 gas derived from a variety of sample types (e.g., air, DIC, carbonates), as well as trace quantities of CO2, and CH4 when the PreCon is utilized. The δ15N and δ18O of dissolved nitrate (converted to N2O using the bacterial method) can also be measured using the PreCon.
