Cyclic Voltammetry (CV) in Characterizing Plating Baths

 The Hull Cell provides a  method for determining if the solutions contain excess brightener.  A sample of the solution can be diluted with a sample containing no additive.  If the plated panel is bright, this provides a good indication that the solution contained excess brightener.  This assumes that the brightness is not improved by dilution of contamination in the solution.    

Cyclic Voltammetry (CV) offers a better solution to determine organic additives (surfactants and brightener contents).   Evaluation of the concentration of organic additives in electrolyte could be obtained using the polarization techniques and stripping voltammetry.  

We have a computer controlled cyclic voltammetry apparatus with a rotating disk electrode setup. 

We can develop evaluation methods to meet your specific plating bath needs, and provide ongoing analysis of your plating baths.
