Electron microscope image quality is greatly improved by the removal of hydrocarbon (H/C) contamination from microscope chambers and from specimen mounts, specimen holders, and the specimens themselves. The Evactron® Decontaminator was developed to clean microscope chambers of their residual H/C contamination.
The Evactron® SoftClean Chamber extends the ability to pre-clean specimens, specimen mounts, and holders with the proven downstream plasma ashing process before examination in the chamber, thus insuring high image quality. The Evactron® SoftClean Chamber can also be used as a specimen storage system, keeping samples in a clean environment.
The downstream plasma process used in the Evactron® SoftClean Chamber is gentle, yet very effective at removing H/C contamination. Sputter etching by other plasma cleaners can damage specimens through exposure to energetic ions and heat.
The Evactron® SoftClean Chamber uses reactive gas radicals to remove H/C from specimen surfaces by chemical etch, preserving critical sample fine structure. This downstream etching process breaks down problematic H/C residues into smaller molecules such as CO2, H2O and CO, which are easily pumped out of the chamber.
