Removal of Humidity by Ionic Liquid Filter to Protect Gas Sensors
Résumé
Air quality has become a hot issue of common concern, particularly BTEX gases (Benzene, Toluene, Ethylbenzene and Xylene). They often cause serious environmental problems and have negative effect on human health even at very low concentration. Gas sensors have been in use for monitoring flammable as well as toxic gases. Since a few years, metal oxide gas sensor are also used to the control and monitor the air quality The detection of gaseous pollutants under real conditions requires working in a humid environment. It is well known that the humidity reduces the performances of gas sensors, particularly in terms of sensitivity. In this work, we demonstrated the possibility to reduce the humidity impact on a metal oxide sensor by using ionic liquid-based filter, without modification of the sensor sensitivity.
