Abstract
The present invention relates to PCGA analytical procedure, in which each PCGA plating/measuring cycle is performed with the stripping and cleaning of test electrode immediately conducted before the equilibrium step, so as to use the metal plate layer formed during a previous plating/measuring cycle as a protective layer for the test electrode. The present invention also relates to PCGA calibration measurement protocol, in which both the calibration measurements and the sample measurement are conducted after a background measurement step.
