Abstract

See full text

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