Removes contamination

remove contamination high vacuum station

The annealing temperature is adjusted by height using the our original thermometer.

A plasma cleaner cannot remove contamination over the entire holder surface, though it is effective for cleaning just the sample. That is, a plasma cleaner cannot perfectly clean the holder; the sample would be re-contaminated by residue materials from the holder shaft when observed by TEM.

Important points

  1. All surfaces of both the holder and sample need cleaning.
  2. Plasma damages the sample.

The LF4 system can clean both your sample and the entire holder surface under light and high vacuum without any sputtering damage. This improves your TEM and STEM data.
