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

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.
