What is the principle of polarography ?

Polarography is an electrochemical method of analysis based on the measurement of current flow resulting from the electrolysis of a solution at a polarisable microelectrode as a function of applied voltage. Polarography is based upon the principle that gradually increasing voltage is applied between two electrodes, one of which is polarisable (dropping mercury electrode) and other is non-polarisable and current flowing between the two electrodes is
recorded. A sigmoid shape current-voltage curve is obtained from which half wave potential as well as diffusion current is calculated. Diffusion current is used for determination of concentration of substance. Half wave potential is characteristic of every element.
