Abstract

A system including an inspection chip equipped with at least a pump connection having a flow path opening for interconnecting to a micro-pump, a flow path through which a fluid flows, and a fluid mixing section for joining and mixing two or more fluids, and including a system body equipped with at least a base body, a chip connection having a flow path opening for interconnecting to the inspection chip, a micro-pump unit in the base body including micro-pumps in substantially the same shape, a detection processor and a controller for controlling at least the functions of the micro-pump unit and the detection processor, and the joining amount ratio is adjusted to set the mixing ratio of two fluids to be joined in the fluid mixing section to be approximately m:n (not 1:1) by making the drive voltages of the micro-pumps substantially equal to each other.
