Abstract
A sheet-type, highly polymerized composite electrode used for measuring ionic concentration includes a thin film ion-selective responsive membrane formed on an upper surface of an insulating support layer by sequentially dripping an ion-selective responsive membrane paste containing solvent onto the support layer. The ion-selective responsive paste has a polymerization degree sufficient to provide an enduring ion-responsive membrane without any reinforcing structure.
Claims7
An improved sheet-type electrode for use in a measurement of ionic concentration, comprising:
- an ion-selective responsive membrane including polyvinyl chloride resin powder having a polymerization degree not less than 3,799 and not greater than 20,001.
A sheet-type electrode for measuring ionic concentration, comprising:
- an insulating support layer having an upper surface and a lower surface, the upper surface of the insulating support layer comprising an ion-responsive substance that is soluble;
- and
- a thin-film ion-selective responsive membrane disposed on the upper surface containing a solvent, the ion-selective responsive membrane being formed by polyvinyl chloride resin having a polymerization degree of not less than 3,799 and not greater than 20,001.
A sheet-type electrode for receiving a liquid sample and measuring the sample's ionic concentration, the electrode being deposited upon an insulating support layer as an ion-responsive membrane paste, the paste being sufficiently polymerized to provide a nonreinforced thin-film ion-selective responsive membrane capable of enduring multiple measurements.
