PURPOSE:In a device of flow cell system for measuring enzyme activity wherein the enzyme activity is measured by one electrode, to improve measurement accuracy, by setting a liquid flow path part to reduce the concentration of substances responsive to the electrode except the enzyme contained in a specimen, connected to an inlet part for a specimen solution. CONSTITUTION:The constant delivery pumps 4' and 4'' are operated, a buffer solution is sent from the buffer solution tank 9 to the flow cell 5, and a substrate corresponding to an enzyme of a measuring object from the substrate solution tank 9 to it. The constant delivery pump 4 is operated, and an enzyme solution of measuring object is sent from the specimen tank 2 to the flow cell 5. The concentration of substances responsive to an electrode except the object enzyme is reduced with an immobilized enzyme, etc. immobilized to the inner wall of the liquid flow path part 8 while the enzyme solution being passed through the liquid flow path part 8. The enzyme is brought into contact with a substrate and reacted with it in a path from the inlet part 10 to the flow cell 5, and the change in concentration of a substance to be detected, decreasing extremely by the reaction, is measured by the electrode 6 of the flow cell 5. |
