ENERGY DISPERSIVE X-RAY FLUORESCENCE (ED-XRF)
INTRODUCTION In
Energy Dispersive X-Ray Fluorescence spectrometry (ED-XRF), the identification
of characteristic lines is performed using detectors that directly measure the
energy of the photons. In energy dispersive X-ray fluorescence
analysis (EDXRF), a ...
