Operation of Wave Dispersed X-ray Spectroscopy and Electron BackScattering
Diffraction (WDS and EBSD operated with Quanta FE-ESEM)

Environmental scanning electron microscope (ESEM) was developed in the mid nineteen eighties. Its primary advantages lie in permitting the scientists to vary the sample environment through a range of pressures, temperatures and gas compositions. The Environmental SEM retains all of the performance advantages of a conventional SEM, but removes the high vacuum constraint on the sample environment. Wet, oily, dirty, non-conductive samples may be examined in their natural state without modification or preparation. The Quanta 200 FESEM offers high resolution secondary electron imaging and back scattering electron image in a gaseous environment of practically any composition, at pressures as high as 6 Torr, and temperatures as high as 1100°C. The Peltier cooling stage provides a working environment at 30°C degrees below ambient temperature, and the combination of low temperature and high water vapor pressure permits you to achieve 100% relative humidity at the sample surface.
