Energy Dispersive X-Ray spectroscopy (EDX) is a spectroscopic procedure for determining the element composition of surfaces. In an electron microscope, electrons bound by the beamed primary electrons are released from the inner energy level of the sample atoms. The free states can be occupied by electrons from outer energy levels. The released energy can be emitted in the form of electromagnetic radiation, whereby this X-ray radiation is characteristic of each element and of the involved energy level (characteristic X-rays). Using EDX, the material composition of a point or area can be quantitatively determined, or spatially resolved measurements can be taken (EDX mapping).
