Energy Dispersive x-ray Spectroscopy (EDS/EDX) is an analytical technique used for the elemental analysis and chemical characterisation of a sample.

When an electron beam is focused onto the area of interest, interactions of the electrons with atoms in the sample result in the generation of x-rays which have an energy which is characteristic of the atom it originated from. When collected using an EDS detector, these x-rays create a spectrum providing quantitative information on the elemental composition of the sample.
