Abstract
An ion-selective electrode comprises, in order of enumerating from the measured-ion contact side: a solid electrolyte as an ion-sensitive membrane; an ionic bridge layer; and, an internal electrode. The bridge layer is prepared by mixing a salt mixture with an electrically conductive resin composition at a ratio of 1:2 to 3:1 in weight, determined after heat treatment. The salt mixture is prepared by mixing silver halide with sodium phosphate at a ratio of from 9:1 to 3:7 in weight. The electrode is very small in voltage fluctuation detected among products; easily downsized to be capable of measuring a very small amount of a sample solution; and useful in measuring activity of ion species such as Na-ion.
