Voltage gradient control system for electrophoresis apparatus
Abstract
Abstract A SYSTEM FOR REGULATING THE MAGNITUDE OF THE ELECTRIC POTENTIAL GRADIENT APPLIED ACROSS THE ACTIVE ELECTROPHORESIS AREA OF AN ELECTROPHORESIS APPARATUS INCLUDING AN ELECTRODE DISPOSED ON EITHER SIDE OF THE ACTIVE AREA FOR MONITORING THE ELECTRIC POTENTIAL GRADIENT BEING APPLIED ACROSS THE ACTIVE AREA, A DIFFERENTIAL AMPLIFIER FOR COMPARING THE AMPLITUDE OF A FIRST SIGNAL DERIVED BY WAY OF THE ELECTRODES WITH A REFERENCE SIGNAL TO PROVIDE A SECOND OUTPUT SIGNAL HAVING AN AMPLITUDE WHICH IS A FUNCTION OF THE DIFFERENCE BETWEEN THE AMPLITUDES OF THE FIRST OUTPUT SIGNAL AND THE REFERENCE SIGNAL AND MEANS RESPONSIVE TO THE SECOND OUTPUT SIGNAL FOR VARYING THE MAGNITUDE OF THE ELECTRIC POTENTIAL GRADIENT BEING APPLIED ACROSS THE ACTIVE ELECTROPHOERESIS AREA.
