Title (EN) ELECTROCHEMICAL SENSOR
(FR) CAPTEUR ÉLECTROCHIMIQUE
Abstract:
(EN) An electrochemical H2S sensor comprises a housing, an electrolyte disposed within the housing, and a plurality of electrodes in contact with the electrolyte within the housing. The plurality of electrodes comprise a porous working electrode that comprises a first surface that is hydrophobic and a second surface that is treated with a surfactant. The first surface is exposed to an ambient gas, and the second surface treated with the surfactant is in contact with the electrolyte.
(FR) L'invention concerne un capteur de H2S électrochimique qui comprend un boîtier, un électrolyte disposé à l'intérieur du boîtier, et une pluralité d'électrodes en contact avec l'électrolyte à l'intérieur du boîtier. La pluralité d'électrodes comprend une électrode de travail poreuse qui comprend une première surface qui est hydrophobe et une seconde surface qui est traitée avec un tensioactif. La première surface est exposée à un gaz ambiant, et la seconde surface traitée avec le tensioactif est en contact avec l'électrolyte.
