Abstract: An electrochemical oxygen sensor includes a sensing surface having a working electrode and a reference electrode, a hydrophilic layer formed from an oxygen diffusion-limiting layer emulsion overlaying the working electrode and a hydrophobic membrane formed from a hydrophobic solution disposed over the hydrophilic layer. The hydrophilic layer contains an epoxy network and a hydrophilic polymer. The hydrophobic layer contains an acetate copolymer and a cross-linking agent that reacts with the liquid epoxy resin in the hydrophilic layer forming the epoxy network where the hydrophobic member is water vapor and oxygen permeable.

Abstract: According to at least one aspect of the present disclosure, a reference half-cell for an electrochemical sensor for measuring a medium is disclosed. The reference half-cell includes a housing defining a chamber containing an electrolyte, the housing including a wall having an aperture therethrough, and an electrode disposed in the electrolyte in the chamber. The reference half-cell further includes a reference junction disposed in the aperture such that an interface between the reference junction and the housing wall is impermeable. The reference junction is electrically or ionically conductive and impermeable to the measured medium and the electrolyte, and the reference junction enables a constant potential at the electrode. An electrochemical sensor and oxidation-reduction potential sensor employing the reference junction are also disclosed.

Abstract: Provided is a gas sensor and methods of monitoring the same. The gas sensor may detect gas restrictions within the gas sensor. The gas sensor may include a test gas diffusion path allowing for monitoring of restrictions within the gas sensor. A pulse of test gas may be electrochemically generated into a void disposed between the membrane and capillary of the gas sensor. The resulting transient signal on the sensing electrode may be analyzed to determine the degree of restriction present in the gas sensor.

Abstract: Disclosed herein are embodiments of a gas sensor system and methods of analyzing data therefrom. In embodiments, a gas sensor system includes one or more gas preconcentrator modules and one or more gas sensor modules. Each gas preconcentrator module includes a substrate that has a top surface having a gas adsorbent material attached to the top surface and has an electrical heater element for heating each preconcentrator module to release adsorb gases to the sensor. The gas sensor modules and the gas preconcentrator modules are in fluid communication with each other. The gas sensor modules responses are readout in parallel multiple times as the preconcentrators are heated yielding a 2-dimensional gas spectrum. The gas sensor output data is analyzed and compared to a library of known data to analyze the gas composition.
