A correction method for an electrolyte measurement system based on the ion-selective electrode method and an electrolyte measurement device equipped with the correction method.

摘要

PROBLEM TO BE SOLVED: To guarantee the accuracy of a measured value in an electrolyte measurement system based on an ion-selective electrode method, it is necessary to correct the measured value using a certified value of a standard product, but the correction mainly used. The method is based on a regression equation, and if the sample has an abnormal value, its accuracy may not be guaranteed. Even if the sample has an abnormal value, its accuracy can be guaranteed. SOLUTION: The difference between the measured value and the certified value of the standard product measured by the electrolyte measurement system is all corrected by the correction coefficient derived as being derived from the difference in the potential between the calibration solution and the standard product.
