Abstract

We presented a membrane focusing concentration method and fabricatedan electro-driving high efficiency,continuous,no-damage focusing electrophoresis concentration device.In the concentration experiments of bromophenol blue and Na-fluorescein,the concentrated efficiencyof the device reached two orders of magnitude.This device can be magnified to industrial equipment with large output.It also can be miniaturized to small and simple attachment for separated and analytical instrument such as electrophoresis,chromatogram, mass spectrum and optical spectrum.When integrated into chips,it would be a pre-concentrated unit of the lab-on-chip.
