ABSTRACT:
The present invention provides a gas detection method and detection apparatus that provide better sensitivity and faster recovery after response than conventional gas detection methods and apparatus, by improving on these conventional methods and apparatus. The present invention is a gas detection method, in which the target gas is detected while oxygen is supplied to a sensor element11aof a metal oxide-type gas sensor11, wherein the target gas is detected while water vapor is supplied to the sensor element11a, and is also a gas detection apparatus equipped with an oxygen supply means14for supplying oxygen to a sensor element11aof a metal oxide-type gas sensor11, said gas detection apparatus being provided with a water vapor supply means15for supplying water vapor to the sensor element11a.
