  • Method of electrophoretic analysis of multicomponent solutions and device for performing the same
    Patent number: 8298393
    Abstract: A device for electrophoretic analysis of multicomponent solutions comprises a capillary and vials for electrolyte and sample solutions. The device comprises streaming potential measurement means implemented to measure a potential difference between capillary ends and to form an electric connections with said capillary ends during capillary rinsing in such a way that said streaming potential measurement means and electrolyte inside capillary and vials form a closed measurement electric circuit. A means for generation of electrolyte flow is implemented so as to build up and maintain a preset differential pressure between capillary ends and wherein that streaming potential measurement means comprises means to disconnect said measurement electric circuit during electrophoretic analysis.
