A method and a device for controlling at least one operating parameter of
an electrolytic bath may provide for the production of improved quality
platings, in which the use of chemicals may be reduced. The concentration
of at least one bath component is determined, and the concentration
values are processed in a control device in order to obtain correcting
variables of a control element, in which the operating parameter is
changed in line with setpoint values. The concentration is determined by
extracting a sample from the bath. The sample is excited by
electromagnetic radiation, and the spectrum of the light emitted by the
sample is analyzed. The device includes an installation for transferring
at least one sample of a bath to an array for determining the
concentration. The array for determining the concentration of at least
one bath component includes a laser directed at the sample, and the array
for determining the concentration includes an array for spectral analysis
of the light emitted by the sample.
