Abstract:
1. A microchip which divides a predetermined amount of a liquid component from an injected liquid and feeds the divided liquid component, comprising: a chip body having an injection hole through which a liquid is injected, and an air vent hole; a first flow passage including an upstream passage connected to the injection hole at an upstream end thereof in a liquid feeding direction, a fixed amount passage linked to the upstream passage and provided with a predetermined volume to store a predetermined amount of a liquid component injected through the upstream passage, and a downstream passage linked to the fixed amount passage and connected to the air vent hole at a downstream end thereof in the liquid feeding direction; a discharging passage whose one end is connected to the downstream end of the upstream passage and other end is configured to be connected to a suction pump configured to discharge a liquid component residing in the upstream passage through the discharging passage; and a liquid feeding passage whose one end is connected to the downstream end of the fixed amount passage; and a reaction chamber having an inlet port connected to other end of the liquid feeding passage and an outlet port configured to be connected to a suction pump configured to feed the predetermined amount of a liquid component from the fixed amount passage to the reaction chamber.
