<p>Method and apparatus (100) are offered which can precisely measure electrolytes without complicating the configuration of the whole apparatus (100), without increasing the amount of the sample solution, and without depending on the concentration of the sample solution. The apparatus (100) has a measuring portion (190) for measuring electromotive forces generated by a reference fluid and the sample fluid, respectively, by the use of an electrode portion (180), a dilution vessel (110) for preparing the sample solution by diluting a sample fluid with a diluting fluid, sample supply means (140) for supplying the sample fluid into the dilution vessel (110), diluting fluid supply means (120) for supplying the diluting fluid into the dilution vessel (110), reference fluid supply means (130) for supplying the reference fluid into the dilution vessel (110), measured fluid supply means (150) for supplying the reference fluid and the sample solution to the electrode portion (180) from the dilution vessel (110), and a control portion (101) for providing control such that the reference fluid and the sample solution are alternately supplied to the electrode portion (180) from the dilution vessel (110) and that a given amount of the diluting fluid is supplied to and wasted from the dilution vessel (110) prior to the preparation of the sample solution.</p> |
