摘要：

A continuous conductometric sensor is described for the determination of carbon dioxide in the atmosphere and innonacidic and nonbasic gases. Gaseous carbon dioxide diffuses through a hydrophobic, gas-porous membrane into a thin layer of pure water. The back wall of the thin water layer is a porous screen that separates the water layer from a mixed-bed ion exchanger column. The ion exchanger continuously removes ionic species from the water layer including the products from the dissociation of CO//2(aq). Conductivity electrodes positioned in the thin water layer measure its conductance.
