We also tried it with little success. However, Dissolved HCO3, CO2, and CO3
concentrations are easy to measure by acid/base titration. Any of the
general geochemistry books (Drever, Stumm & Morgan, Langmuir etc) have the
methodology. We use a digital titrator and pre-packed reagents from by Hach
(worldwide suppliers of this type of kit) which is very easy to use and do
our DIC measurements in the field.
