摘要
PROBLEM TO BE SOLVED: To perform oxidation-reduction current measurement in a polarographic system or in a galvanic cell system without using a drive mechanism, accurately and stably.;SOLUTION: An oxidation-reduction current measuring electrode unit comprises: a support chip 1 having a first surface 1a and a second surface 1b opposite to the first surface; a detection electrode 2 provided on the first surface 1a of the support chip 1 and immersed into a sample solution; a counter electrode 3 attached to the support chip 1 and immersed into the sample solution; and a shield 4 arranged so as to surround the detection electrode 2 and blocking the flow of the sample solution in contact with the detection electrode 2. The shield 4 is a cylindrical body having a peripheral surface across the first surface 1a to the second surface 1b of the support chip 1, and is opened on a lower end side and an upper end side.;COPYRIGHT: (C)2015,JPO&INPIT
