1. Carbon and nitrogen isotopes in solid organic materials (e.g., fish tissue, plant material, soils and sediments, rocks).
2. Oxygen isotopes of water (fresh and saline). Please contact the lab manager about sample collection methods.
3. Carbon isotopes of dissolved inorganic carbon (DIC). Note, DIC concentrations must be >0.5mM and special collection techniques are required. Please contact the lab manager to discuss sample collect.
4. Carbon and oxygen isotopes of calcium carbonate (e.g., foraminifera, bivalves, otoliths, soils/rock/sediments).
5. Carbon and oxygen isotopes of pure carbon dioxide gas.
6. Nitrogen isotopes of pure nitrogen gas.

If you don’t see what you are looking for please contact the laboratory manager.
