viva 1.1 (for process analysis)
Glossary
Analysis volume
If a sample is diluted, then that part of the dilution volume (see Glossary,
page 1051) that is added to the measuring vessel is referred to as analysis
volume (see Glossary, page 1057).
Baseline
Auxiliary line for the calculation of the evaluation quantities (peak area,
peak height) from the beginning of the steep increase of the peak to the
end of the steep decrease of the peak. The peak area and the peak height
are calculated between the baseline and the curve.
Brightener
see Brightener
Brightener
In electroplating bath analysis, "brightener" refers to an organic additive
that increases the plating rate of metals. Because even small quantities of
brightener can significantly increase metal plating, this characteristic effect
can be used to determine the brightener concentration in an electroplat-
ing bath.
CP (chronopotentiometry)
In the CP measuring mode with the option Measure galvanostatically
(see Glossary, page 1046), a constant current is applied to the working
electrode (see A) and the diffusion-controlled change in the electrode
potential over time is measured (see B).
In the CP measuring mode with the option Measure open-circuit
potential (see Glossary, page 1055), the circuit is opened and the
potential between the working electrode and the reference electrode is
measured during the indicated measurement duration (see B).
