ABSTRACT:
Analytical methods are disclosed for determining the quantity of brightener and leveler in an electroplating bath in the presence of other organic additives, such as accelerators, brighteners and suppressors. The methods improve the reproducibility of measuring brighteners and levelers in electroplating baths.
