発明の名称 (英語) Electrode module
発明の概要(英語) An electrode module includes a working electrode, a counter electrode, a reference electrode and a well (container) for retaining an electrolytic solution and is used in electrochemical measuring instruments.
This electrode module is produced by integrating the well with at least one of the working electrode, the counter electrode and the reference electrode.
This integrated electrode includes a chip-like electrode having a thin membrane of an electrode material formed on the surface of a chip-like base metal.
This chip-like electrode is disposed on and integrated with the bottom of the well in a detachable manner.
There is provided the compact, low price electrode module of high repetition use efficiency with no need of maintenance and having easy handling.
特許請求の範囲(英語) [claim1]
1. An electrode module for use in an electrochemical measuring instrument comprising: an electrode chip comprising a chip-like metal base on which is a thin film of electrode material formed by any one of depositing, sputtering, and printing; and
a well for retaining an electrolytic solution and having a bottom, the well being positioned in an electrode holder,
wherein the electrode chip is disposed on and integrated with the bottom of the well in a detachable manner so as to form at least part of an internal surface of the well,
wherein an electrode holding ruler is used to fix the electrode chip to the well, the electrode holding ruler having a planar base and parallel slits along two opposing side walls of the base,
wherein the electrode module further comprises an electrode presser and a conductive plate, the electrode presser being made from an elastic, electrically conductive resin rubber, and the conductive plate having a clamping portion which engages a groove in the electrode holder,
wherein the conductive plate is positioned on the electrode holding ruler, the electrode presser is positioned on the conductive plate, and the electrode chip is positioned on the electrode presser.
[claim2]
2. The electrode module of claim 1 wherein the electrode chip is a working electrode chip.
[claim3]
3. The electrode module of claim 1 wherein the electrode chip is a counter electrode chip.
[claim4]
4. The electrode module of claim 1 wherein the electrode chip is a reference electrode chip.
