Japanese Patent JP5642137
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide an apparatus for preparing a solution capable of controlling suction and discharge means on the basis of a change of a property of a mixed solution.SOLUTION: An apparatus for preparing a solution includes: a first storage tank 10 and a second storage tank 12 which respectively store a first liquid and a second liquid, where the first liquid and the second liquid are different in at least one of the solute, solvent, concentration and hydrogen ion concentration; a first pump 14 and a second pump 16 which suck and discharge the first liquid in the first storage tank and the second liquid in the second storage tank in a synchronized state via independent flow channels; a mixing column 26 for mixing the first liquid and the second liquid; a solution storage tank 30 for storing a mixed solution which is a mixture of the first liquid and the second liquid; detection means for detecting at least one of the discharge flow rate and discharge pressure of the first and the second pumps and a characteristic value of the mixed solution; and controlling means for controlling the first and the second pumps on the basis of the detection value of the detection means.
