Determination of brighteners in copper baths with the help of IC and Metrohm Inline Cation Removal in addition to column switching technique
Summary
Special brighteners are used in electroplating baths in order to provide the refined surfaces with greater brightness. The concentration of brighteners must be kept constant at all times in order to ensure uniform end product quality. This Application Note describes how brighteners are determined in parallel with IC and CVS. The corresponding CVS application can be found under AN-V-183.
