Abstract
The ion sensor of the present invention is a current measurement type ion sensor that measures a current to measure a target ion, and includes an organic phase retaining layer containing an organic phase capable of forming an interface with the sample containing the target ion, a first electrode to which the organic phase retaining layer is laminated and containing a first insertion material composed of an inorganic compound, a second electrode arranged so as to face the organic phase holding layer and in contact with the sample.
Claims21
An ion sensor of current measurement type that measures a current to measure a target ion, comprising:
- an organic phase retaining layer containing an organic phase capable of forming an interface with a sample containing the target ion;
- a first electrode containing a first insertion material including an inorganic compound to which the organic phase retaining layer is laminated;
- and
- a second electrode arranged to face the organic phase retaining layer and in contact with the sample, wherein
- the first electrode further contains a solid electrolyte,
- the first insertion material and the solid electrolyte of the first electrode are particles, and
- a ratio of an average particle size of the particles of the solid electrolyte to the average particle size of the particles of the first insertion material is 0.001 or more and 0.3 or less.
