GAS ANALYZER

摘要

An alkali ion conductive solid electrolyte electrochemical concentration cell assembly for measuring gases containing anhydrides or related compounds in air or in oxygen-bearing gases is divided into two identical alkali ion conductive half cycles. Each half cell is secured to opposite surfaces of the closed end of a solid membrane exhibiting alkali ion conductivity corresponding to the alkali ion conductivity of the half cells. The membrane effectively isolates a monitored gas environment contacting one half cell from a reference gas environment contacting the other half cell while supporting the equilibrium mode of operation of the concentration cell assembly to generate an electrical signal indicative of a gas species of interest in the monitored gas environment.
