MICROCHIP LIQUID FEEDING SYSTEM

摘要

[Technical Problem] It is an object to provide a microchip solution sending system that is provided with the high reaction efficiency and the high detection accuracy even in the case in which a solution amount of the specimen material solution is small. [Solution of Problem] A microchip solution sending system that is configured in such a manner that a specimen material solution (36) that has been sent passes through a detection region (20) in a repetitive manner in the case in which a micro pump (40) sends the specimen material solution (36) to a flow passage assembly (A) in a reciprocating manner; comprising a solution sending amount measurement means (42) that is configured to measure the amount of a solution that is sent from the micro pump, and a solution sending direction control means (44) that is configured to reverse the solution sending direction of the micro pump, wherein in the case in which the amount of a solution that is sent from the micro pump is measured by the solution sending amount measurement means (42) and the measured amount of the sent solution reaches a predetermined amount of the sent solution, the specimen material solution that has been sent passes through the detection region in a repetitive manner in a state in which the detection region (20) is filled with the specimen material solution (36) on a constant basis by reversing the solution sending direction by using the solution sending direction control means (44).
