摘要

#CMT# #/CMT# The method involves utilizing a gas sensor (114) that comprises a mixed potential cell with a mixed potential electrode (134) with mixed potential behavior, where the mixed potential electrode and an electrode (136) exhibit a connection between the electrode and a solid electrolyte (120). The mixed potential electrode is pressurized with gas from a gas measuring chamber (112). The mixed potential electrode is used for two different functions, where the two functions comprise a mixed potential measurement for detecting a gas component. #CMT# : #/CMT# An independent claim is also included for a device for detecting gas components in a gas measuring chamber. #CMT#USE : #/CMT# Method for detecting gas components e.g. oxygen, nitrogen oxide, carbon oxide and carbon monoxide, reducing gas, oxidisable gas, hydrocarbon and nitrogen hydrogen compound such as ammonia (all claimed) in a gas measuring chamber. #CMT#ADVANTAGE : #/CMT# The mixed potential electrode is used for two different functions, where the two functions comprise the mixed potential measurement for detecting the gas components, thus detecting various gas components in gas measuring in a qualitative and/or quantitative manner. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a sectional view of a device for detecting gas components in a gas measuring chamber with a nitrous oxide measuring function. 112 : Gas measuring chamber 114 : Gas sensor 120 : Solid electrolyte 134 : Mixed potential electrode 136 : Electrode.
