Abstract

An ion sensor has a flow path through which a sample flows. An ion-exchange membrane is in contact with the sample in the sample flow path. An internal solution is provided on one side of the ion-exchange membrane. An internal electrode is provided so as to come in contact with the internal solution. The surface of the ion-exchange membrane that does not come in contact with the sample is coated with a two-liquid-mixed epoxy resin.

Claims (6)

1. An ion sensor comprising a flow path through which a sample flows, an ion-exchange membrane so provided as to come in contact with the sample in said sample flow path, an internal solution provided on one side of said ion-exchange membrane where it does not come in contact with the sample so as to come in contact with said ion-exchange membrane, and an internal electrode provided so as to come in contact with said internal solution, which are arranged in a sealed container, wherein the surface of said ion-exchange membrane that does not come in contact with the sample is coated with a reaction-type adhesive.

2. An ion sensor comprising a flow path through which a sample flows, an ion-exchange membrane so provided as to come in contact with the sample in said sample flow path, an internal solution provided on one side of said ion-exchange membrane where it does not come in contact with the sample so as to come in contact with said ion-exchange membrane, and an internal electrode provided so as to come in contact with said internal solution, which are arranged in a sealed container, wherein the surface of said ion-exchange membrane that does not come in contact with the sample is coated with a two-liquid-mixed epoxy resin.

3. A chloride ion sensor comprising a flow path through which a sample flows, a chloride ion-exchange membrane so provided as to come in contact with the sample in said sample flow path, an internal solution provided on one side of said chloride ion-exchange membrane where it does not come in contact with the sample so as to come in contact with said ion-exchange membrane, and an internal electrode provided so as to come in contact with said internal solution, which are arranged in a sealed container, wherein the surface of said chloride ion-exchange membrane that does not come in contact with the sample is coated with a two-liquid-mixed epoxy resin.

4. A clinical analyzer using an ion sensor of claim 1 .

5. A clinical analyzer using an ion sensor of claim 2 .

6. A clinical analyzer using an ion sensor of claim 3 .
