Difference between wdxrf and edxrf

WebEnergy Dispersive XRF (EDXRF) and Wavelength Dispersive XRF (WDXRF). The main difference between these two types of spectrometer lies in the information detected, as the technique names say, in the EDXRF, the energy of different X-rays photons are detected, whereas for WDXRF, it is the wavelength of different X-rays photons that is detected. WebThe principle advantages of WDXRF systems are high resolution (typically 5 – 20 eV) and minimal spectral overlaps. X-ray optics can be used to enhance WDXRF instrumentation. For conventional XRF …

WebAug 20, 2013 · All it takes is a simple three-minute analysis under vacuum to achieve a precision of less than 1 % relative standard deviation (RSD) for all major components. Needless to say an EDXRF spectrometer can accurately measure Zn, Pb, Ba, Fe and Si in a variety of sulfide ores, and avoids the difficulty, expense and delays associated with ... WebTheory of X-ray fluorescence. In X-ray fluorescence (XRF), an electron can be ejected from its atomic orbital by the absorption of a light wave (photon) of sufficient energy. The energy of the photon (hν) must be greater than the energy with which the electron is bound to the nucleus of the atom. When an inner orbital electron is ejected from ... Weblike WDXRF, the EDXRF signal (fluorescence intensity) is not usually linearly proportional to concentration, because of small X-ray absorption and enhancement effects brought about by other elements present in the sample. These so-called ‘matrix effects' can be overcome by the same correction procedures used in WDXRF spectrometry, where free borders with transparent background
