  • Electrochemical solid electrolyte sensor for the detection of oxygen, hydrocarbons and moisture in vacuum environments
    Publication number: 20060254908
    Abstract: A contaminant molecule sensor for the detection of oxygen, hydrocarbons and humidity comprises an electrochemical cell for use in vacuum, The cell comprises a measurement electrode (2), a reference electrode (3) and a solid-state ionic species conductor (1) bridging the measurement electrode and the reference electrode. The measurement electrode comprises a catalyst selected for its ability to catalyse the dissociation of a contaminant’ molecule into its ionic species. The reference electrode comprises a catalyst selected for its ability to catalyse the dissociation of a reference molecule into its ionic species. The conductor is selected to conduct an ionic species common to the dissociated contaminant and reference molecules.
