Energy Dispersive X-Ray Spectroscopy (EDS)

Energy Dispersive X-Ray Spectroscopy (EDS) is an analytical technique which is available on our Transmission Electron Microscope (TEM), Scanning Transmission Electron Microscope (STEM), FIB/SEM(Dualbeam) and all our Field Emission Gun Scanning Electron Microscopes.

When an electron beam interacts with a specimen characteristic x-rays are produced. The energy and number of the X-rays emitted can be measured using an EDS detector.

Within LMCC all the EDS detectors are silicon drift detectors and therefore can achieve a high count rate, which reduces the acquisition time. It also provides the ability to reduce the beam current which will reduce the ineraction volume produced by the electron beam and provide better resolution for the lighter elements such as Carbon and Boron.
