摘要： A gas sensor having first and second electrodes, an ion conducting solid electrolyte membrane positioned therebetween, first and second electrically conductive gas diffusion layers, first and second electrode contact members for electrically coupling said first and second electrodes to an external circuit, a water reservoir, a gas entry passageway and a water permeation barrier for controlling the transport of water vapor to the ion conducting solid electrolyte membrane. The water permeation barrier is a thin walled member which allows water vapor to diffuse therethrough and evaporate from an exit surface, the thickness of the water permeation barrier controlling the internal relative humidity of the sensor. A method for adjusting the present sensor in-situ due to changes in the current humidity conditions of the sensor so as to keep the gas sensitivity loss within a predetermined range is also disclosed.

摘要： Embodiments herein provide a membrane that is a product of a phenol crosslinked with one or more compounds containing an allyl group. The phenol may be electropolymerized with the allyl-containing compounds to form the crosslinked polymer. Suitable allyl-containing compounds include allylphenol, allylalcohol, allylamine, and allylcarbamide. A membrane may have one type of allyl-containing compound, or, alternatively, two or more types of compounds. As used in an analyte sensing device, a membrane formed from a crosslinked phenol may provide improved interference exclusion, peroxide response, stability, and/or solvent resistance.

摘要： A hydrogen detector with a porous layer of alumina. Pores with average pore diameters in the range of from about 10 to about 200 nanometers (nms) and average pore depths in the range of from about 10 to about 1000 nms have Pd nanoparticles in the pores forming a film. Electrodes on the Pd film measure changes in electrical resistance of the Pd film in the presence of hydrogen. Pd may be in the form of nanotubes. The alumina is anodized for various times to form the nanowalls or pores and vary the pore depths.

摘要： Method and apparatus for detecting and/or determining ethanol in fluid samples using a substantially non-porous barrier of un-plasticized polyvinyl chloride (PVC) interposed between the sample to be analyzed and a detecting means responsive to ethanol. The ethanol diffuses through the barrier membrane and then is measured at the detecting means. The PVC membrane can be made by solvent casting, and is usually 10 to 40 um thick. Measurement can be by any known means, but preferably electrochemically (amperometrically). The PVC membrane may be part of a multiple membrane system. The method and sensor are useful for analyzing alcoholic liquors or beverages (for example beer, wine and other fermentation products), in their final form or at intermediate stages of their manufacture or storage, and also for the monitoring of a wide range of process, waste and effluent liquids.
