<P>PROBLEM TO BE SOLVED: To provide an electrochemical measuring apparatus which is capable of accurately measuring target substances even if a plurality of kinds of target substances are contained in one sample solution. <P>SOLUTION: An apparatus for electrochemically detecting or measuring a plurality of kinds of target substances contained in the same sample solution S is provided. The apparatus comprises an operating electrode 2, potential fluctuating means 7 which fluctuates a potential of the operating electrode 2 in a predetermined direction, supplies a potential to electrodeposit the target substances on a surface of the operating electrode 2, then fluctuates the potential of the operating electrode 2 in an opposite direction and supplies a potential to elute the target substances electrodeposited on the surface of the operating electrode 2, and a counter electrode. A plurality of pairs of the operating electrodes 2 and the potential fluctuation means 7 are provided, certain potential fluctuation means 71 supplies a potential to electrodeposit predetermined one kind of target substance A onto the surface of an operating electrode 21 paired therewith. After the electrodeposition is completed, other potential fluctuation means 72 supplies a potential to electrodeposit a target substance B onto the surface of an operating electrode 22 paired therewith. <P>COPYRIGHT: (C)2013,JPO&INPIT |
