Abstract

PURPOSE:To make it possible to perform continuous measurement with excellent measuring accuracy and sensitivity in the coulometric titration method using soid electrolyte having conductivity for oxygen ions, by using the combination of the cells having the same structure (a sample is put in one cell). CONSTITUTION:The two cells having the structure shown by the Figure is prepared.[The solid electrolytes 1 and 2 are constituted by providing platinum electrodes and the like on both surfaces of ZrO2(CaO) and the like, respectively; II shows a sample chamber;Ishows a part wherein reference gas is present when the partial pressure of the oxygen in the sample chamber is measrued; and III shows the part supplying oxygen to the sample chamber.]Then the sample is inputted into the sample chamber of only one cell. Both cells are kept at the same temperature. Then, the electromotive force between the electrodes of the solid electrolyte 1 is detected. A current is flowed to the solid electrolyte 2 in both cells so that the values of the electromotive forces of both cells becomes equal. By using the difference in the curent values flowing in both cells and the electromotive forces, the coulometric titration is performed.
