Latest Patents

Chie Masuda holds a patent for an ion-selective electrode. This electrode comprises, in order 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 consists of silver halide mixed with sodium phosphate at a ratio of 9:1 to 3:7 in weight. This innovative electrode design is characterized by minimal voltage fluctuation among products, making it capable of measuring very small amounts of sample solutions. It is particularly useful for measuring the activity of ion species such as Na-ion.
