PURPOSE:To microform the electrode by forming a high-polymer film contg. an ion sensitive agent on the surface of a solid electrode by using an electrolytic polymn. method. CONSTITUTION:A measuring instrument consists of the solid electrode 1, a polymerized film 2 formed thereon, a reference electrode 3, a potentiometer 4 and a soln. A to be measured. A wire-shaped electrods is more preferable for the purpose of microforming the electrode 1. The film 2 is formed by the electrolytic polymn. method and includes the ion sensitive material taken in during the polymn. reaction. The generation of a potential difference between the modification electrode 1 and the reference electrode 3 according to the activity of the desired ion contained in the soln. A to be measured is utilized and the activity of the ion is determined from this potential difference by using a previously formed calibration curve. |
