Abstract

A dual pump and a buffer pump have been integrated on a silicon wafer for chemical analyzing systems. These pumps realize constant and rippleless liquid flow of a small volume. The controllable flow rate of the pumps was up to about 40 μl/min and the maximum pumping pressure was about 1 mH₂O. A sample injector made up of two three-way valves has also been fabricated with micromachining.
