energy analyzer

energy analyzer

An energy analyzer is used to disperse energies of characteristic X-rays or soft X-rays in WDS, and those of inelastically scattered electrons in EELS. In the case of WDS, analyzing crystals and gratings are respectively used for characteristic X-rays (element analysis) and for soft X-rays (measurements of the density of states of the valence band). In the case of EELS, an omega filter is used as an incolumn type energy analyzer, and a sector analyzer is used as a post-column type energy analyzer.
