Abstract
A microchip has a substrate on which there are formed a reaction bath section, a first flow channel to which are connected a supply channel that supplies a buffer solution and the reaction bath section, a second flow channel to which are connected a supply channel that supplies a sample solution containing a first substance and a channel that discharges the sample and buffer solutions to an exterior of the substrate, and a connecting channel connecting the first flow channel to the second flow channel. The reaction bath section receives the first and second substances so that the first and second substances react in the reaction bath section. The first and second flow channels are provided with valves disposed relative to the connecting channel such that selective opening and closing of the valves causes the buffer solution to flow first into the reaction bath section at a preselected speed and the sample solution to flow second into the reaction bath section at the preselected speed to cause the first and second substances to react in the reaction bath section.
