Development of a Microfluidic Device for Performing Sample Preconcentration and Capillary Electrophoresis Separation
نویسندگان
چکیده
We report on a microfabricated device for sample preconcentration and capillary electrophoresis (CE) separation in a glass microchip. The device allows highly efficient anion-selective preconcentration to be performed with a micro-nanomicrochannel structure. An integrated cross channel enables gate-injection of the preconcentrated sample into the analysis channel for CE separation. Sample preconcentration and corresponding enhanced CE separation signal have been demonstrated with TRITC-tagged peptides.

متن کاملOn-line sample preconcentration by large-volume sample stacking with an electroosmotic flow pump (LVSEP) in microscale electrophoresis.
This review highlights on-line sample preconcentration by large-volume sample stacking with an electroosmotic flow pump (LVSEP) in microscale electrophoresis. LVSEP requires only a hydrodynamic sample injection into the whole capillary/microchannel and a constant voltage application, i.e., without polarity switching, providing an efficient sensitivity enhancement with a relatively easy experime...
