Analytical Electron Microscopy: Analytical Electron Microscopy is a generic term that is applied to any study where a variety of analysis techniques are used within one particular microscope. These techniques typically include X-ray Energy Dispersive Spectroscopy (XEDS), Electron Energy Loss Spectroscopy (EELS), Selected Area Electron Diffraction (SAED), Convergent Beam Electron Diffraction (CBED), Scanning Transmission Electron Microscopy, and Scanning Electron Microscopy. These techniques are briefly described in the glossary.
