    摘要： The present invention is characterized by a solid body disposed so that a remarkably small gap may be formed between it and a surface of an electrode. A super-thin liquid membrane is formed in the small gap by an interfacial tension of a liquid. An object to be measured is applied to or acted upon either the solid body or the super-thin liquid membrane. An electric signal due to the physical properties of the super-thin liquid membrane itself or an electric signal due to a chemical or physical reaction, which is generated on an interface of the solid body and the super-thin liquid membrane and diffused through the super-thin liquid membrane itself, is detected by means of the electrode to measure the physical properties of the object to be measured.

    摘要： A flat shaped composite electrode includes a flat substrate having a high electrical insulating property. A flat inside pair of electrodes and a flat outside pair of electrodes are fixed on the substrate. A flat support layer having a high electrical insulating property overlays the electrodes and substrate. The support layer describes two holes into which a gelatinized internal solution is placed. An ion response glass membrane is mounted on the support layer and over one hole, while a liquid junction membrane is similarly mounted over the other hole.

    摘要： A method of measuring an ion-concentration characterized by a sample absorbed in an easily absorbing solution material and the absorbing material is brought into contact with a measuring portion to measure an ion-concentration 10/90 in the sample so that a highly accurate measurement can be achieved even though a quantity of the sample is small. In addition, the desired measurement can be carried out without using any instruments for sampling and needing any complicated pretreatments. A sheet for use in the calibration of an ion-concentration 10/90 measuring device characterized by a calibrating buffer solution absorbed in a chemically stabilized, hygroscopic, water-absorbing sheet eluting no ions and then the water-absorbing sheet is dried.

    摘要： An improved electrode assembly of a modular configuration for sensing ion concentration includes a substrate mounted in a housing and being sandwiched by a first and second support layer of non-conductive material. A gelantinized solution is positioned in an opening between the first support layer and a substrate, while a second gelatinized solution is positioned in an opening between a second support layer and a substrate. Electric leads and electrodes are appropriately positioned on the substrate for operative contact with the respective gelatinized solutions. An ion-responsive member contacts one gelatinized solution, while an acqueous junction member extends through the respective support layers and substrates to contact another gelatinized solution.

    摘要： In a sheet type reference electrode having a gelatinized internal solution, a liquid junction surface of the gelatinized internal solution is coated with a hydrophilic porous thin film. Alternatively, a liquid junction member contacts the gelatinized internal solution and is coated with a hydrophilic porous thin film. In either event, the thin film controls the diffusion of ions from the gelatinized internal solution. A liquid junction portion is also provided by impregnating a chemically stabilized, hydrophilic, high molecular porous material with a gelatinized composition which remains wet.
