Wavelength Dispersive X-ray fluorescence (WDXRF) is a well established technique in the metals industry and in particular in the iron and steel industry. Its versatility in handling both conducting and non-conducting solids, its accuracy and excellent precision for the majority of the elements and the wide dynamic range (from ppm to 100 percent) give WDXRF the place it enjoys in the metals industry today, in conjunction with the spark-excited optical emission technique. Elemental analysis of raw materials, intermediate products (sintered, calcinated or electrolysis related) and final products (pure metals and alloys) is routinely carried out using a typical configuration with about 15 to 20 XRF monochromators for rapid analysis and an XRF goniometer for flexible analysis of other elements.
