Analysis of Electroless Nickel Plating Baths Using ICP-OES With DSOI

Electroless nickel plating is widely used across industries such as automotive, aerospace, and electronics for its ability to enhance surface properties like corrosion resistance and hardness. The stability and performance of these plating baths are highly dependent on their chemical composition. Accurate elemental analysis is therefore essential to detect impurities, maintain bath consistency, and extend operational lifespan.

This application report demonstrates how inductively coupled plasma optical emission spectrometry (ICP-OES) with Dual Side-On Interface (DSOI) plasma observation enables precise, simultaneous detection of major and trace elements in complex plating matrices. The method ensures high sensitivity, excellent matrix tolerance, and minimal sample preparation—making it ideal for routine quality control in demanding environments. The study also highlights the successful determination of stabilizing elements such as bismuth and antimony, offering a safer alternative to traditional mercury-based techniques.
