<P>PROBLEM TO BE SOLVED: To solve a problem in a potential difference measurement device that it has been found that a certain time period (response time) is required to generate a potential value conforming to a Nernst formula, and this response time tend to elongate with repeated use of the device. <P>SOLUTION: The potential difference measurement device includes a sample solution holding section; a measurement electrode which is brought into contact with the sample solution to be introduced into the sample solution holding section, and on which molecules each having a hydrophilic group and molecules each having an electrochemical active material are aligned and coupled with each other; a reference electrode to be brought into contact with the sample solution to be introduced into the sample solution holding section; and a potentiometer for measuring a potential difference between the measurement electrode and the reference electrode. <P>COPYRIGHT: (C)2012,JPO&INPIT |
