AU143: Determination of Chloride in Acid Copper Plating Bath Be the first to rate this application

chloride acid copper plating bath


Ion chromatography provides a convenient method for the determination of chloride in acid copper plating baths. Monitoring chloride concentration is of interest because it plays an important role in the quality of copper deposition. Compared to standard wet chemical techniques, IC offers improved speed and accuracy for this analysis. Chloride is separated from the excess of sulfate present in the copper plating bath. Chloride is detected by suppressed conductivity and the EG40 eluent generator is used to prepare the 30 mM potassium hydroxide eluent on-line.
