XRF method for rapid plating solution analysis

Typically used for measuring coating thickness, the X-Ray Fluorescence (XRF) method offers a fast, simple and unskilled analysis of plating solutions, according to Fischer Instrumentation.

The quality of the solution in a plating bath plays a vital role in the deposition of a plated coating.

The solution is depleted with use and in some processes it is contaminated by the items being plated, especially if the solution is acid-based.

In Zn-Ni baths, for example, Fe is dissolved from the steel components, contaminating the solution.

The concentration of the metal ions is indicative of the solution's condition and obviously plays a vital role and must be monitored.

The traditional analysis methods are titration and Atomic Absorption Spectroscopy (AAS).

The XRF method uses the same X-ray system that is used for measuring coating thickness in most plating companies and is proving to be a fast, simple and cost-effective alternative for analysing plating solutions.

Following research by the Helmut Fischer Group's physicist, Dr Simone Dill, Ray Scruby, managing director of Fischer Instrumentation (GB), explains the difference between XRF and more traditional methods of analysing plating solutions in the full article found at Fischer's website.

Energy dispersive X-ray fluorescence (EDXRF) is a versatile technology for quick, non-destructive qualitative and quantitative multi-element analysis and coating thickness measurement.

Due to the range of elements that can be detected, the range of applications for X-ray instruments reaches from industrial applications to research and science.
