Our lab is based around making rapid and precise determinations of carbonate system parameters. These instruments are set up to run environmental samples of total alkalinity and DIC, the δ13C and δ1818 of DIC, and the δ13C and δ18O of CaCO3. We also have a membrane inlet mass spectrometer (MIMS) which we use to determine the activity of the enzyme Carbonic anhydrase (CA) in natural samples.
WHOI Plasma Mass Spectrometry Facility
We occasionally use inductively coupled plasma mass spectrometers (ICP-MS) to make measurements of metals in seawater and in carbonate shells. You can see the facility here
