    摘要: An ion-selective electrode comprises an ion-sensing membrane, an internal electrode adhered to the ion-sensing membrane, and a lead connected to said internal electrode. The internal electrode used comprises a plurality of metallic wires arranged into a grating or a mesh. The wires comprises a metal core and a surface layer of a salt of the metal. The metal of the core is silver and the salt of the metal is a silver halide selected from the group consisting of silver bromide, silver chloride and silver iodide. At least a part of the internal electrode is buried inside the ion-sensing membrane. Various components, the ion-sensing membrane, the internal electrode, the lead, an external terminal, are disposed in a flow-through cell having a flow path formed therein, through which path a sample solution is passed, to constitute the ion-selective electrode. In the flow-through cell is disposed a means of maintaining the humidity to feed water vapor therefrom to the ion-sensing membrane. This structure, even when the ion-sensing membrane has a complicated configuration such as concave or convex surface, enables the establishment of good adhering conditions between the internal electrode and the ion-sensing membrane while retaining the complicated configuration of the ion-sensing membrane without reducing the effective contact areas of the ion-sensing membrane and the internal electrode.

    摘要: Infrared radiation is incident on a total reflection plane of a prism and penetrates a liquid sample through a metal layer put between the total reflection plane and the liquid sample in close contact therewith whereby the infrared radiation is partially absorbed by the liquid sample. Alternatively, the liquid sample may be put between the total reflection plane and the metal layer in close contact therewith so that part of the light penetrates the sample from the prism through the total reflection plane to interact with the metal layer and then is caused to reenter into the prism whereby it is partly absorbed by the liquid sample. The metal layer is for enhancing the intensity of the electric field component of the infrared radiation. The incident angle of the infrared radiation on the total reflection plane is so set that the partially absorbed infrared radiation is total-reflected. The total-reflected infrared radiation is detected by a detector so as to obtain an absorption spectrum of the liquid sample by the infrared radiation.

    摘要: A gas sensor e.g. an oxygen sensor for testing body fluids, has a laminated structure with a cavity for holding a gel or liquid electrolyte in contact with a cathode and anodes formed by deposition on layers of the structure. The cathode contacts the electrolyte cavity only at a small-volume reaction region defined e.g. in a groove which communicates with a larger, laminar volume of the cavity formed e.g. by a spacer layer having through apertures. A small gas-permeable window opposes the cathode at the reaction region. The laminar construction can be mass-produced. The enlarged electrolyte reservoir lengthens the sensor life.
