Abstract
The present invention relates to a method for selectively detecting and/or measuring gaseous SOat a temperature of at least 500° C., the method involving: (i) providing a SO-detecting device including an oxygen ion-conducting substrate having on its surface at least three electrodes comprising a first, second, and third electrode; (ii) driving a starting current of specified magnitude and temporal variation between the first and second electrodes; (iii) contacting the SO-detecting device with the SO-containing sample while maintaining the magnitude and any temporal variation of the starting current, wherein said SO-containing sample causes a change in the electrical conductance of said device; and (iv) detecting the change in electrical conductance of the device based on measuring an electrical property related to or indicative of the conductance of the device between the first and third electrodes, or between the second and third electrodes, and detecting SOin the SO-containing sample based on the measured change in electrical conductance.
