Instrument Description:

A CO2 coulometer semi-automatically controls the sample handling and extraction of CO2 from seawater samples. Samples are acidified and the CO2 gas is bubbled into a titration cell where CO2 is converted to hydroxyethylcarbonic acid which is then automatically titrated with a coulometrically-generated base to a colorimetric endpoint.

PI supplied instrument name: UIC 5400
Dataset-specific description

Total alkalinity (TA) and dissolved inorganic carbon (DIC) were analyzed via coulometry (UIC 5400) and via closed-cell potentiometric Gran titration, respectively (Marianda, VINDTA 3C) calibrated with certified Dickson DIC/TA standards (Scripps Institution of Oceanography; San Diego, California, USA).
