I am looking for a method to determine small amounts of CO2 dissolved in aquatious solutions, how is this usually done?

Concentrations are typically 0-5 mg/L and I have not yet found any equipment or method capable of determining such small concentrations, even though this is the concentration in natural waters.

I am mainly interested in the CO2-form, but total inorganic carbon would also be of interest.
