Abstract

PURPOSE:To measure a specimen with high sensitivity and high accuracy by removing the interaction between an electrode for detecting the quantity of a substance to be measured and an electrode for detecting the quantity of a measurement obstructing substance, by providing both electrodes in a mutually separated state. CONSTITUTION:The electrode 8 for detecting the quantity of a substance to be measured is constituted by providing a platinium electrode on which glucoseoxidase is imobilized, as an working electrode 8a and a Ag-AgCl electrode as a counter electrode 8b. As the acting electrode 7a of an electrode 7 for detecting the quantity of a measurement obstructing substance, a platinum electrode is provided and a Ag-AgCl electrode is provided as a counter electrode 7b. The electrodes 8, 7 are separated through a liquid passing part (l) so as to generate no interaction. Then, a buffer solution 1 is sent and a specimen is introduced from an injection port 6 and both of them are sent to the electrodes 7, 8 at a constant flow speed. The quantity of the substance to be measured is calculated by subtracting the current IA corresponding to the quantity of the obstructing substance at the electrode 7 from the current IB corresponding to the sum of the quantities of the substance to be measured and the obstructing substance at the electrode 8. Because the electrodes for respectively detecting the substance to be measured and the obstructing electrode are provided, highly accurate measurement is enabled.
