EDS (Energy-Dispersive X-ray Spectroscopy)

Energy-Dispersive X-ray Spectroscopy (EDS) is an analytical technique used to identify the elements present in a material. When a sample is hit with high-energy electrons, it emits X-rays with energies characteristic of the elements in the sample. By measuring these energies, EDS determines which elements are present and their amounts. This method is commonly used in materials science, chemistry, and geology to analyze the composition of samples at microscopic levels, providing detailed elemental information without destroying the sample.
