Kalousek

Polarography with superimposed AC signal. As examples of chemical analytical importance we shall consider (a) sinusoidal AC, (b) AC bridge, (c) square-wave and (d) Kalousek polarography. 

Tensammetry, although originally a sinusoidal ac polarography, is not limited to that technique, but has been applied also to the Kalousek-type wave form45 and to square waves46 ... 

Fig. 3.50. Kalousek polarography on an incrementally growing potential background, (a) K3, (b) K4.

With the Kalousek computer polarograph, a programmable real-time clock (with rates up to 1 MHz) and an operational amplifier were used, and the computer had to perform the following functions ...
