Abstract:
1. A method of measuring electrolytes by an electrolyte measuring apparatus having: a measuring portion for measuring electromotive forces generated by a reference fluid and a sample solution, respectively, by the use of an electrode portion having working electrodes and a reference electrode; a dilution vessel for preparing the sample solution by diluting a sample fluid with a diluting fluid; reference fluid supply means for supplying the reference fluid into the dilution vessel; diluting fluid supply means for supplying the diluting fluid into the dilution vessel; sample supply means for supplying the sample fluid into the dilution vessel; and measured fluid supply means for supplying the reference fluid and the sample solution alternately to the electrode portion from the dilution vessel; comprising two processes each including four steps performed in turn: wherein, when the reference fluid and the sample solution are alternately supplied to the electrode portion and measured, a given amount of the diluting fluid is supplied to and wasted from the dilution vessel prior to the preparation of the sample solution.
