FLOW-RATE CONTROLLED SURFACE CHARGE COATING FOR CAPILLARY ELECTROPHORESIS

摘要

a process produces an electroosmotic flow with desired characteristics in a capillary tube (22) is provided with groups of surface charge.an electrolyte solution (28), which contains a compound capable of altering a stable charge is drawn into the tube wall of the tube (22), for the control of the electroosmotic flow so as to obtain the flow tube electro osomotique.we can use this method to optimize the electrophoretic separation of charged species of proteins or nucleic acids in a capillary tube and to produce capillary tubes with desired properties of charge density.
