The Electron Microscopy Unit was established as one of major research facilities provided by Qatar University to serve those students and faculty who pursue advanced research projects utilizing electron microscopic techniques. The unit has constantly been used since 1992. It has two electron microscopes, a Transmission Electron Microscope (TEM) Philips CM12, with resolution of 0.35 nm and a screen magnification of X750K and a FEI Quanta 200 Environmental Scanning Electron Microscope (ESEM) with a resolution of 5 nm and a magnification X200K. The Scanning Microscope is also equipped with an Energy Dispersive X-ray analysis system (EDX) for semi quantitative analysis of elements. A number of specimen preparation equipment are available for material and biological samples.
