Abstract: PROBLEM TO BE SOLVED: To provide a method for measuring concentration of component to be measured by which the concentration of a component to be measured in a sample solution containing the component and its interfering component can be measured quickly and accurately. SOLUTION: At the time of measuring the hydrogen peroxide concentration of the sample solution, a concentration-reduced sample solution is prepared by keeping the sample solution in a decomposing tank 4 for a fixed period of time while the solution is vibrated by means of a vibrating motor 6. A spectroscopic analyzer 8 measures the intensity Is of an ultraviolet ray transmitted through the sample solution after the ray is radiated at a prescribed intensity and the intensity Ig of the ultraviolet ray transmitted through the concentration- reduced sample solution after the ray is radiated at the prescribed intensity. Then the hydrogen peroxide concentration of the sample solution is computed quickly and accurately without being affected by the interfering component by utilizing the proportional relation between -log (Is/Ig) and the hydrogen peroxide concentration.

Abstract: A plurality of fluids are accurately and quickly mixed such that a target characteristic is attained. A fluid control device is provided with flow channels (5, 7, 11,13) for allowing a plurality of to-be-mixed fluids to flow; flow channels (15, 17) for allowing a mixed fluid to flow; a pump (19) for shifting the fluids in the flow channels; flow rate adjusting units (11b, 13b) for respectively adjusting flow rates of a plurality of to-be-mixed fluids; a measuring unit (15a) for optically measuring a characteristic of the mixed fluid; and a control unit (21) that controls the flow rate adjusting units (11b, 13b) to adjust the flow rates of the to-be-mixed fluids based on a result of the measurement of the measuring unit (15a), such that the mixed fluid attains a target characteristic.
