ANALYSIS SYSTEM, MICROCHEMICAL CHIP USED THEREIN AND LIQUID DRIVING METHOD

摘要

PROBLEM TO BE SOLVED: To enhance the adsorbing efficiency of an analyzing substance on an adsorbent, using a low-cost and simple constitution, and a method. SOLUTION: This analyzing system is equipped with a microchemical chip, which is equipped with a mixture flow channel for mixing a plurality of kinds of mixture materials and the absorbent charged in the mixture flow channel in a movable manner and capable of adsorbing a predetermined analyzing substance in the mixed liquid prepared by mixing a plurality of kinds of the mixture materials; a micropump, capable of allowing the liquid mixture of the mixed liquid and the adsorbent in the mixture flow channel in the positive direction from the upstream side of the mixture flow channel to the downstream side and the reverse direction from the downstream side of the mixture flow channel to the upstream side thereof; and a control system for stirring the liquid mixture in the mixture flow channel by controlling the liquid driving of the micropump.
