Abstract

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.<>
