Integrated electroosmotic pumps and flow manifolds for total chemical analysis systems

Following the trend towards smaller channel inner diameter for better separation performance and shorter channel length for shorter transport time, construction of miniaturized components for a total chemical analysis system using microlithographic methods is proposed. The system might include the so-called electroosmotic flow pump and valveless switching of flowpaths. An example structure for such a system, based on flow injection analysis and electrophoresis, is presented.<
