Abstract: A catalytic resistance element for use in a gas analyzer has an outer layer formed of particles of a metallic oxide, such as beryllium or aluminum, of about one micron average size, the outer layer preferably being of from about 100 to about 500 microns in thickness. The oxide particles have catalytic coatings formed by mixing the particles with a solution of a compound which is decomposed by heating to coat the particles with the catalyst and heating the mixture to cause such decomposition and coating. The outer layer is applied by mixing the oxide particles with binder solution, and applying drops of the mixture to the resistance element.
