Multielectrode solid electrolyte amperometric sensors are considered as an effective instrument for such measurements in hazardous working conditions. This paper presents basic principles and experimental results on the analysis of combustibles in the presence of oxygen by means of zirconia electrolyte amperometric cells. Experimental studies are concerned with electrochemicaloxidation of carbon monoxide, methane and propene in the presence of oxygen in different working conditions at different types of electrodes. Results show diverse opportunities for selective performance of different electroanalytical reactions at certain electrodes |
