  • Gradient elution electrophoresis
    Patent number: 8080144
    Abstract: A method for performing electrophoretic separation of ionic compounds which involves varying a bulk fluid flow though a separation path into which ionic species are continuously introduced and separated. The method can also include the introduction of a leading electrolyte into the separation path to form an ionic interface with the sample and an optional terminating electrolyte to enrich ionic species for higher detection resolution.
    Type: Grant
