<P>PROBLEM TO BE SOLVED: To provide an electrochemical measuring method which enables the simple measurement of a target component by neither providing a permselective membrane for obstructing an inhibition component nor especially measuring the response current due to the inhibition component, and a measuring apparatus using it. <P>SOLUTION: In the electrochemical measuring method for detecting the current signal associated with the electrochemical oxidation or reduction of the target component by applying potential to an acting electrode using an electrode system composed of the acting electrode, a reference electrode and a counter electrode, at least two potentials different in value selected so that the current signals due to the oxidation and reduction of the target component are different and the concentration of the target component contained in a sample is calculated from the difference between at least two obtained response currents different in value. The current signal produced by the oxidation or reduction of a substance other than the target component can be removed by this method. The electrochemical measuring apparatus is also disclosed. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
