Planar chips technology for miniaturization and integration of separation techniques into monitoring systems

Miniaturization of already existing techniques in on-line analytical chemistry is an alternative to compound-selective chemical sensors. Theory on separation science predicts higher efficiency, faster analysis time and lower reagent consumption for microsystems. Micromachining, a well known photolithographic technique for structures in the micrometer range, is introduced. A first capillary electrophoresis experiment using a chip-like structure is presented.
