Determination of Oxides of Carbon in Hydrogen-Nitrogen Mixtures Continuous Determination of Minute Concentrations by Eiectroconductivity

Abstract

An electroeonductometric analyzer for the continuous, separate, or simultaneous determination of carbon dioxide and carbon monoxide in concentrations of 0 to 100 p.p.m. in hydrogen-nitrogen mixtures and the application of the analyzer to the analytical control of the TVA synthetic ammonia plant are described. An absorptionconductivity cell of new design and a recording alternating current Wheatstone bridge are employed. Carbon monoxide, after oxidation by an improved iodine pentoxide reagent, is determined as carbon dioxide. Full operating details are given.
