Abstract

Multiple redox gas detection such as carbon monoxide, nitrogen monoxide and oxygen by solid electrolyte gas sensors (SESs), operated in a dynamic detection regime, is reported. To this aim, an oxygenpumping SES was used in cyclic voltammetry mode at different operational conditions and gas concentrations. The obtained results demonstrate the possibility of selective detection of CO and NO in nitrogen gas flow with one device.
