Waveform Generation and Frequency Resolution

Posted by Dominik on August 25, 2016

This Technical Note outlines how waveform signals are generated with a potentiostat. Further, the term “frequency resolution” is discussed which is often mentioned in specification sheets for potentiostats.

Determination of the correct value of Cdl from the impedance results fitted by the commercially available software

Posted by gamry on March 11, 2015

With the introduction of a constant phase element (CPE) as a replacement for the capacity in EIS measurements, most of the experimentally obtained results could be fitted by commercially available software.
