| abstract | PURPOSE: To enable rapid measurement in the state of whole blood after collecting by providing a piece of porous bridge on the ion selective layers of two kinds of ion selective electrode pairs. n CONSTITUTION: The measuring instrument consists of an upper frame 1, porous liquid distributing members 21, 22, a water impermeable member layer 3, the carbonic acid ion selective electrode pairs 41A, 42A, the pH electrode pairs 41B, 42B and a lower supporting frame 5. A reference liquid having a known concn. of carbonic acid ions and pH value is supplied through the member 21 and the liquid supply holes 31A, 31B to the electrodes 41A, 41B when the above-mentioned reference liquid is spotted to a liquid spotting hole 101 and a liquid sample is spotted approximately simultaneously to a liquid spotting hole 102. The liquid sample is similarly supplied through the member 22 and the liquid supply holes 32A, 32B to the electrodes 42A, 42B. On the other hand, the boundary faces of the reference liquid and the liquid sample come into contact with each other near the center of the porous bridge 100, thus forming a liquid junction. The potential differences corresponding to the difference in the concn. of the carbonic acid ions and pH between the reference liquid and the liquid sample are thereby generated between the electrodes 41A and 42A and between 41B and 42B. The potential differences are measured and the concn. of the carbonic acid ions and pH value in the liquid sample are determined by the calibration curve, etc., based on the actually measured values. n COPYRIGHT: (C)1989,JPO&Japio |
