3. Pulse methods in polarography
Impulse methods were developed in the 1960s to overcome the problem of sensitivity of conventional polarography due to the capacitive component of the measured current, which makes it unsuitable for concentrations well below 10 –5 M. Several methods have been developed, differing in the way the potential is applied to the mercury electrode. The...
