EELS can be used for elemental analysis since the edges occur at the energy losses corresponding to the binding energies of the core electrons in the elements, and the integrated intensity under the edge depends on the number of atoms penetrated by the incident electron beam. Different from EDS, EELS can provide elemental data on all the light elements except H and He, although the latter had been detected under certain conditions, e.g., in nanometer-sized He bubbles in irradiated Ni alloys [1].
