A selective ammonia sensor

Abstract A systematic study of the gas-sensing characteristics of a large number of semiconducting oxides has shown that the degree of specificity of gas response varies greatly between materials. In particular, chromium sesquioxide containing a small amount of titanium exhibits a resistance increase when exposed to ammonia in air, but shows no significant response when exposed to comparable concentrations of hydrogen, carbon monoxide or methane.
