<P>PROBLEM TO BE SOLVED: To provide a very easy method for electrochemical measurement of organic solvent test liquid to achieve a measured value with quick response, stable indication and high reliability, and a comparison electrode and a combined electrode to be used for the same. <P>SOLUTION: The electrochemical measurement method for the organic solvent test liquid uses a measurement electrode 2 and the comparison electrode 1. It also uses a comparison electrode internal liquid having a concentration precluding the deposition of crystals when contacting the object organic solvent test liquid. The comparison electrode 1 usable for electrochemical measurement of the organic solvent test liquid has a comparison electrode internal liquid storage part 10 and a liquid junction part 12 for permitting the flow of the liquid out of the storage part 10 to the outside. The storage part 10 stores the comparison electrode internal liquid 13 having the concentration precluding the deposition of the crystals when contacting the object organic solvent test liquid. <P>COPYRIGHT: (C)2004,JPO |
