CPVS - Cyclic Pulse Voltammetric Stripping
General:
CPVS or Cyclic Pulse Voltammetric Stripping is used to de-
termine organic additives in electroplating electrolytes. The CPVS
measuring mode can be set for the exploratory and determination
mode by selecting CPVS - Cyclic Pulse Voltammetric Stripping for
the Mode parameter in the EXPLORATORY SPECIFICATION or
WORKING METHOD SPECIFICATIONS window.
Description:
For Cyclic Pulse Voltammetric Stripping, the potential of an RDE
(e.g. Pt) is changed between different potentials in pulsed, discrete
steps in a plating bath. The current i is measured as a function of
the time t. The curves registered in the last cycles are stored and its
peaks can be evaluated using linear or horizontal baselines.
