Energy dispersive X-ray fluorescence (2.14)

Student's Manual Energy dispersive X-ray fluorescence spectrometry is used to analyze a sample's elemental composition. Using the energies of characteristic X-rays, Moseley's Law will be verfied which is a direct evidence for the existence of Atomic number.
