Energy Dispersive X-ray Spectroscopy (EDS) is an analytical technique used for the elemental analysis or chemical characterization of a sample. It relies on the interaction between X-rays and the sample to generate characteristic X-rays that are unique to each element. When the sample is bombarded with high-energy electrons, it causes the ejection of inner-shell electrons, creating vacancies. Electrons from higher energy levels then fill these vacancies, emitting X-rays in the process. The energy of these emitted X-rays is measured and used to identify and quantify the elements present in the sample.

EDS is widely used in conjunction with Scanning Electron Microscopy (SEM) and Transmission Electron Microscopy (TEM) to provide detailed compositional information at microscopic levels. This technique is essential in various fields such as materials science, geology, and biology for tasks like identifying contaminants, analyzing failure mechanisms, and studying the composition of complex materials.

This course provides the participants with an advanced knowledge on Energy Dispersive X-ray Spectroscopy and desires to expand their knowledge on data interpretation in-order-to equip themselves for a more accurate qualitative and quantitative analysis.
