Example 3
In order to preserve components after solvent cleaning, corrosion protection oils are used. The
corrosion protection of the components is influenced by the concentration of the corrosion protec-
tion oil in the solvent. Since the concentration decreases due to the process, it must be monitored
and re-dosed. The first figure shows the correlation between measured fluorescence intensity and
the concentration of the corrosion protection oil in the solvent. The second figure shows measured
bath samples before and after dosing.
