摘要： A biochemical analysis apparatus comprises a movement device which moves analysis media containing a reagent or an electrochemical sensor, which will interact with a specific biochemical substance contained in liquid samples and give rise to changes in the analysis media, along a movement path connecting an introducing section and an ejecting section. While the analysis media are present in the movement path, a measurement device measures changes which have occurred in analysis media. A reading device reads information about correction values, which are to be used in order to correct a calibration curve so that it becomes suitable for analysis media used in analyses, from a correction value recording medium. A correction device corrects the calibration curve on the basis of the correction values. An operation device uses the corrected calibration curve in order to determine the concentration or the activity of the specific biochemical substance in a liquid sample from the value measured by the measurement device.

摘要： A device for determining ionic activity composed of, as essential components, plural pairs of ion-selective solid electrodes each pair having two electrodes (one electrode on each of two sides) and each pair having a different ion-selective layer; two liquid distribution porous members, each member disposed over all the electrodes of each said side of the plural pairs; and a porous capillary bridge disposed on or between the liquid distribution porous members. The bridge can be in liquid contact with all the electrodes through the liquid distribution porous members and achieve electrical conduction between two electrodes in each pair after spotting a test solution and a reference solution. The device preferably further comprises a support frame and a cover having two apertures for liquid spotting. The device can simultaneously determine ionic activities of a plurality of different ions in a test solution, such as whole blood, plasma, serum, urine, etc., by spotting a test solution and a reference solution each in one operation and measuring an electrical potential difference of each pair.
