Patent ID: 7909063

Claim:
A microchip inspection system for use with a driving liquid, the microchip inspection system comprising: a micro pump to inject the driving liquid from a liquid flow path into a microchip; a liquid temperature adjusting section to adjust a liquid temperature of the driving liquid; a driving liquid detecting section to detect presence or absence of the driving liquid at two predetermined positions located in the liquid flow path, so as to output detection signals; a fluid velocity calculating section to calculate a fluid velocity based on the detection signals outputted by the driving liquid detecting section; a liquid temperature controlling section to control the liquid temperature adjusting section, based on the fluid velocity calculated by the fluid velocity calculating section; a driving liquid tank to store the driving liquid; wherein the driving liquid tank is equipped with the liquid temperature adjusting section; and the liquid temperature adjusting section is structured to adjust the temperature of the driving liquid in the driving liquid tank while the driving liquid is in the driving liquid tank.
