ABSTRACT:
An electrolyte anion exchange sensor having a first diffusion membrane is spaced apart from an anion exchange membrane to form a cathodic cell. A second diffusion membrane is spaced apart from the anion exchange to form an anodic cell. CO.sub.2 flows through the first membrane and is ionized. The bicarbonate ions flow through the anion exchange membrane into the anodic compartment and reacts to form CO.sub.2. The current change in the electrolyte path corresponds to the amount of CO.sub.2.
