Brighteners /carriers concentration can be analyzed by qualiplate CVS (cyclic
voltametric stripping). However for gold plating baths this does not apply.
Usually brighteners in gold plating baths are not being analyzed, they were just
be added in direct proportions with gold content in a bath. So if you know the
gold content, you have the idea how much brightener you will add.]

Hope this helps

Subject:  [TN] Plating processes




Anyone have any input about how to analyze carriers
and brighteners in plating baths? What about potential
problems with gold plating?

I'll probably have more plating process questions as I
get deeper into my project so if the experts can offer
any advice I'd appreciate any help.

Thanks, Jack
