MICROCHIP REACTION DETECTION SYSTEM AND METHOD OF REACTION OF MICROCHIP IN FLOW PATH
First Claim
1. A microchip reaction detection system comprising:
- a microchip comprisinga driving liquid injection unit into which a driving liquid for driving a solution is injected anda detection unit on which a reacting substance is supported and in which the reaction between the reacting substance and the solution is detected;
a driving liquid pump for injecting the driving liquid into the driving liquid injection unit;
an air pump for injecting a gas into the detection unit; and
a control unitfor controlling the driving liquid pump so that the driving liquid can be injected into the driving liquid injection unit and controlling the air pump so that the gas can be injected into the detection unit intermittently of at least an amount effective for pushing away the solution injected into the detection unit while feeding the solution to the detection unit.

Abstract
Disclosed is a microchip reaction detection system comprising: a microchip comprising a driving liquid injection unit into which a driving liquid for driving a solution is injected and a detection unit on which a substance to be reacted is supported and where the reaction between the substance and the solution is detected; a driving liquid pump for injecting the driving liquid into the driving liquid injection unit; an air pump for injecting a gas into the detection unit; and a control unit for controlling the driving liquid pump so that the driving liquid can be injected into the driving liquid injection unit and also controlling the air pump so that the gas can be injected into the detection unit intermittently in an amount at least effective for pushing away the solution injected in the detection unit while feeding the solution to the detection unit.

3. A method of reaction inside a flow path of a microchip,
wherein the reaction is carried out by feeding a solution to a wall of a flow path which supports a reacting substance in the detection unit and by contacting the reacting substance with the solution, and wherein the solution and a gas of at least an amount effective for pushing out the solution injected into the detection unit are alternatively injected into the detection unit at the time of the reaction.
