摘要

PROBLEM TO BE SOLVED: To provide a method which enables the simple measurement of catecholamines with high sensitivity in a highly selective manner without being affected by impurities.;SOLUTION: Catecholamines are measured using an electrochemical cell, which is constituted so that a first acting electrode containing a metal oxide for oxidizing catecholamines and the second acting electrode provided in a close vicinity to the first acting electrode and formed of a metal or carbon for reducing oxidized catecholamines are integrated in a fine flow channel, while continuously sending a measuring sample through the fine flow channel.;COPYRIGHT: (C)2007,JPO&INPIT
