THE HISTORICAL ROLE OF XRF IN THE SOLUTION OF INDUSTRIAL PROCESSES
International Centre for Diffraction Data
Since the renascence of X-ray fluorescence in the mid-1940’s the technique has played a valuable role in the solution of industrial problems. In the early days most of the applications involved analysis
of finished materials to ensure adherence to specification, and checking for impurities. Early industrial applications were mainly found in the non-ferrous metal and oil industries. In the late-1950’s the development
- of XRF on-stream analyzers offered hitherto undreamed of control in ore extraction and benefication processes. With improvement in instrumentation the accuracy, sensitivity
- and range of the technique were greatly improved allowing an even wider range of industrial applications. The flexibility of the XRF method has always made it a valuable trouble shooting and problem-solving tool. This paper highlights the more important examples of these applications.
