Title
(EN) METHOD OF MEASURING GAS CONCENTRATIONS AND MICROFABRICATED SENSING DEVICE FOR PRACTICING SAME
(FR) PROCEDE DE MESURE DE CONCENTRATIONS DE GAZ ET DISPOSITIF CAPTEUR MICROFABRIQUE UTILISE A CET EFFET
Abstract
(EN)
A microfabricated sensing device is disclosed, including methods for using the same for measurement of the concentration of a gas in a sample. Unique sensor configurations are described which substantially eliminate electrode cross-contamination during operation of the microfabricated sensing devices.
(FR)
Dispositif capteur microfabriqué et procédés de mesure de la concentration d'un gaz dans un échantillon utilisant ce dispositif. On décrit des configurations uniques de capteur qui éliminent virtuellement la contamination croisée des électrodes pendant le fonctionnement de ces dispositifs capteurs microfabriqués.
