New Tool to Unravel Interactions Between Gas and Sensitive Surface Through the Simultaneous Characterization of Gas Uptake and Electrical Properties of the Material
Résumé
This work presents an innovative setup for simultaneous determination of (i) electrical gas sensor response and (ii) uptake of target gas on sensitive material. Operating under atmospheric pressure and at 298K, it is designed to work under a wide range of gas flow, relative humidity and target gas concentration. Results validate the system effectiveness in monitoring gas uptake and sensor responses simultaneously, offering insights into physicochemical processes related to gas detection.
