In contrast to 'normal' SEM, in environmental scanning electrom microscopy (ESEM)

  • samples are analysed in a gaseous environment and not under vacuum
  • wet samples can be analysed which is crucial for live biological samples
  • the samples do not have to be conductive (with conducting carbon or gold)
  • faster and easier analysis
  • gas/liquid/solid interaction can be analysis in real time and in situ

The instrument also allows for a large temperature differences in the sample chamber which widens the scope of the technique.
