Extract

The incoherently and coherently scattered X-ray intensities with the corresponding scatter factors have been used previously define in a sample matrix the light elements (Z<12) constituents which can not be a s sessed via their fluorescent radiation in conventional XRF. Recently, a more complete sample definition has been achieved based on the backscattered X-rays, by using two excitation modes. However, all quantitative EDXRF methods, based on the scattered radiation from the sample relied hitherto uniquely on the use of monochromatic excitation radiation.
