polarography

 [po″lar-og´rah-fe]
an electrochemical technique for identifying and estimating the concentration of reducible elements in an electrochemical cell by means of the dual measurement of the current flowing through the cell and the electrical potential at which each element is reduced. adj., adj polarograph´ic.

po·lar·og·ra·phy

(pō'lăr-og'ră-fē),
That branch of electrochemistry concerned with the variation in current flowing through a solution as the voltage is varied; this will vary with the ionic concentration of reducible substances so that polarography can be used in chemical analysis. Polarography is commonly employed in the form of a reduction at a dropping mercury electrode.
