1-38. (canceled)
A method for determining a concentration of a gaseous analyte in an enclosed space using an amperometric gas sensor, the amperometric gas sensor comprising a solid support configured for diffusion of the analyte therethrough, and a working electrode in contact with the solid support, wherein prior to being contacted by the analyte the solid support comprises an insulator, and the analyte comprises a dopant which when in contact with the solid support increases the electrical conductivity of the solid support, the method comprising:
- placing the amperometric gas sensor in the enclosed space;
- flowing the analyte in the enclosed space in contact with the sensor;
- and
- determining the concentration of the analyte in the enclosed space using the amperometric gas sensor.
