Among the physico-chemical methods used in medicine is the polarographic analysis (PA), first proposed by Academician J. Geirovsky. PA is based on determining the dependence of the current strength on the applied voltage during electrolysis of a solution in a special electrolyzer. The current-potential relationship is expressed graphically in the form of polarization curves (polarograms). Each electroactive substance under certain conditions (background electrolyte solution) has its reduction potential. The half-wave potential of the polarogram (electrode potential at which the current value equal to half of the limiting diffusion current is reached) reflects the qualitative feature of the substance.
