PURPOSE:To stabilize the characteristic of an anion selective electrode having an ion sensitive part consisting of silver halide for a long period of time by incorporating preliminarily the silver halide into a soln. which contacts with an ion sensitive membrane at the satd. concn. or above at the temp. thereof. CONSTITUTION:The silver halide is preliminarily incorporated into a sample liquid 9 to be inspected and calibration liquids 5, 6 which contact with the ion sensitive film 1' in the stage of measuring, cleaning and calibrating as well as a diluting liquid 4 held at above the temp. possessed by the liquid 4 in common use as the cleaning liquid at the satd. concn. or above at the temp. thereof in a method for analysis in which the anion selective electrode 1 having the ion sensitive membrane 1' consisting of the silver halide is used. The satd. soln. of the silver halide is thus formed from the ambient temp. conditions when the calibrating liquid for correcting the output potential from the electrode and the cleaning liquid for cleaning the flow passage for the sample to be tested arrive at the ion sensitive part, by which the elusion of the silver halide from the ion sensitive part is prevented. |
