Electron Microscope

Learn about the electron microscopes we use for elemental analysis.

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.

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.

Cryo-SEM

The Quorum Technologies PP2000T system allows the examination of hydrated samples. A sample can be rapidly frozen before being transferred under vacuum into the SEM for observation.
