device for the extraction of kapillarelektrophorese separate samples on a membrane

摘要

An electrode structure is provided for isolating a solute sample which has been analyzed by capillary electrophoresis. The apparatus comprises an electrically conductive layer connected to a source of electrical energy, an porous layer containing an electrically conductive electrolyte positioned on the conductive layer, and a capillary tube in contact with the porous layer. The sample exiting from the capillary tube is retained by the porous layer under the influence of a voltage induced at the conductive layer.
