PURPOSE:To perform a high-sensitive and high-precise analysis of ion, by observing a change in response potential of an ion selective electrode outputted corresponding to an applied trigger pulse. CONSTITUTION:An ion selective electrode 6, showing a response potential to a solution concentration through perception of an ion to be measured, and a comparison electrode 7, indicating a reference potential to the response potential of the electrode 6, are immersed in an ion-to-be-measured solution 2. Further, a trigger electrode 3 is immersed in the solution 2. An analysis of ion to be measured is conducted through observation of the change in response potential of the electrode 6, produced by applying a trigger voltage to the electrode 3, by means of a wave-form display unit 11 and a Fourier series analyzer 12. This permits the simple application of a trigger voltage to the electrode 3 from the outside, and the electrode 6 indicates a response in a particular wave-form. |
