Development of a selective carbon monoxide sensor

In this work, the regularities of the oxidation of combustible substances (H 2 , CO, CH 4 , and gasoline vapors) in the presence of metal oxides are revealed and catalysts for the sensitive elements of selective carbon monoxide sensors are selected on their basis. The possibility of creating a highl...

Description
Summary:In this work, the regularities of the oxidation of combustible substances (H 2 , CO, CH 4 , and gasoline vapors) in the presence of metal oxides are revealed and catalysts for the sensitive elements of selective carbon monoxide sensors are selected on their basis. The possibility of creating a highly selective sensor using measuring and compensating heat-sensitive elements containing catalysts of different activity to the components of gas mixtures has been experimentally confirmed. The main characteristics of the developed selective carbon monoxide sensors are evaluated. The use of such sensors reduces the error of analysis, increases the instrument readings’ stability and service life, and improves reproducibility and selectivity in the continuous automatic determination of gas components in the measurement area.
