in one easy clean....

 
     

 

 
 

This radical improvement in image quality was achieved with a single clean.

This Indium-on-Iron sample was prepared in vacuum, but even so was susceptible to image degradation through contamination. The FEG on which this data was run was 5 years old.

  • Plugs into the EM chamber directly
  • Cleans not only the sample but surrounding instrument areas, so improving overall performance
  • Better than Cryo-trap! Gently and actively removes contamination
  • Completely different process to "plasma pre-prep" because it is a chemical (oxygen radical) cleaning process. This makes it extremely gentle compared with the usual "high-energy bombardment" process inherent in immersing the sample in a plasma.
  • Port Adapters available for most popular EMs
  • Extremely cost-effective
