Electron Microscope Facility

The core instruments of the Electron Microscope Facility are the Hitachi S-4700 Field Emission Scanning Electron Microscope (SEM) with Quorum Technologies Cryo-system, and the Philips CM30 High Resolution Transmission Electron Microscope (TEM). Both have x-ray analytical capability for elemental analysis.


The SEM in use

SEM

The Hitachi S-4700 is a cold field emission high resolution scanning electron microscope. Capabilities include secondary electron (SE) and backscattered electron (BSE) imaging. It is equipped with an energy dispersive x-ray system which allows both qualitative and quantitative elemental analysis.
