【発明の名称】流体中の原子又は分子の濃度を測定するための電気化学的アナライザ及びその製造方法
Document Type and Number:
Japanese Patent JPH03502238
Kind Code:
A
Abstract:
A solid-state electrochemical analyzer, for measuring the concentration of atoms or molecules in a first fluid or gas as compared with a second fluid or gas, features an insulating tube formed with at least one longitudinal bore therethrough extending from one end, constituting the fluid inlet end of the tube, to the opposite end of the tube, means for directing the first fluid to flow into the longitudinal bore so that the longitudinal bore serves as a path of flow for the first fluid, means defining an outlet for the first fluid, means for directing the second fluid to flow through a second path with respect to the insulating tube, a solid electrolyte, conductive to the ions of the atoms or molecules to be measured, deposited in the insulating tube to bridge the paths of flow of the two fluids, and an electrode, at each of the interfaces of the solid electrolyte with the respective fluid, for outputting an electrical signal generated in the solid electrolyte, the signal corresponding to the concentration of the atoms or molecules in the fluids.
