Measuring apparatus of two components using enzyme electrodes and the measuring method thereof.

摘要

In a two-component measuring apparatus employing a first enzyme electrode (4) responding only to a first component to be measured and a second enzyme electrode (6) responding to both first and second components to be measured, in which the enzymatic reactions for forming detectable substances are common and the substances to be finally detected by the electrodes (4, 6) are identical, when calculating the calibration curve for the second component to be measured, the output portion due to traces of the first component contained in the second component to be measured is removed, so that the second component is measured at high sensitivity and high accuracy.
