Abstract
A method is disclosed for determining carbon dioxide content in gaseous or liquid samples. A semi-permeable membrane-type sensor comprising a sensor electrode, reference electrode and an electrolyte having a pH range of 9.5-11.0 or 10.7-12.0 is used. Potential between the electrodes is monitored as a measure of carbon dioxide in the sample. When an electrolyte having a pH range of 10.7-12.0 is used the electrolyte additionally contains at least 255 v/v of a water miscible solvent having dielectric constant of a least 10.
