Process elemental analysis of chemical baths

AppNote XRF1306: aqueous chemical bath containing Ni, Co, Mo, Zn, In


Measurement of aqueous chemical bath solutions containing nickel, cobalt, molybdenum, zinc and indium is demonstrated. Surface treating is an important part in the manufacture of copper foil for the electronics industry. Surface treatments are used to clean the copper foil, to create roughing and heat resistance treatments, and to make single or multiple layer thin film coatings to prevent oxidation or enhance the electro-chemical properties of the copper foil. The chemical baths must be constantly monitored to ensure the highest quality surface treatments. Rigaku offers the NEX OL analyzer to meet these analytical needs for trend analysis of bath composition.
