PURPOSE: To provide an electrolyte analyzer in which a stable concentration response output is obtained by an ion selection electrode and by which a measuring system can be processed at a high speed. CONSTITUTION: A living-body sample is introduced into an ion selection electrode block 30, and an electrolyte in the sample is measured. A sample introduction block 32 which has a heating function is arranged at the previous stage of the electrode block 30, and the sample introduction block 32, the electrode block 30 and a reference electrode 31 are housed inside a thermostatic bath 33 which maintains a constant temperature. A syringe 4 which decides the flow velocity of the sample in such a way that the sample passing the sample introduction block 32 is preheated so as to be brought close to the temperature of an ion selection electrode and which temporarily stops the preheated sample inside the ion selection electrode, is provided. The temperature of the sample inside the ion selection electrode is set so as to become to be substantially the same temperature as that of an ion selection electrode film by means of the flow velocity of the sample and by means of the temporary stop of the sample inside the ion selection electrode. |
