A Brief Introduction to SEM Scanning Electron Microscopy SciMed.
WhatCreates the Electrons Used in SEM? There are three ways of generating the electrons that SEM instruments use.: Field emission gun - this generates a powerful electric field, which pulls electrons away from their atoms and generates high resolution images.
Scanning Electron Microscopy SEM Analysis EAG Laboratories.
Coupled to an auxiliary Energy Dispersive X-ray Spectroscopy EDS detector, SEM also offers elemental identification of nearly the entire periodic table. EAG uses SEM analysis in cases where optical microscopy cannot provide sufficient image resolution or high enough magnification. The SEM also excels in producing detailed surface topography images.

The scanning electron microscope SEM can also be useful to reveal morphological features of isolated organisms as well as for diagnosis, but difficulty with specimen preparation methods have in the past limited the use of SEM for routine microbiology 7, 8.
Microbeam School of Earth Sciences University of Bristol.
The scanning electron microscope SEM provides a service to the Earth and Environmental science community as well as to all departments within the University of Bristol. The SEM is run in conjunction with two electron microprobes, which enables us to provide a full range of electron and x-ray imaging, together with in-situ chemical analysis of both major and minor elements heavier than carbon.
