ENVIRONMENTAL SCANNING ELECTRON-MICROSCOPY

The ElectroScan environmental scanning electron microscope (ESEM) is o ne of the most exciting new developments in the field of Electron Micr oscopy. The ESEM differs from conventional Scanning Electron Microscop es (SEM) by being able to examine materials including liquids and oils in their natural state with no prior sample preparation. Accessory eq uipment, cooling, heating and manipulating devices allow the manipulat ion of samples thus making it possible for the first time to image dyn amic processes such as wetting, drying, absorption, corrosion, melting , crystallisation, curing and fracturing at high magnification.
