3.1.3. Comparison of different cleaning procedures
A comparison of the outgassing of samples with applied differ-
ent cleaning procedures after the PT mentioned in Section 2.4 has
shown no essential influence of the cleaning procedures. All sur-
faces could sufficiently be cleaned with cleaner and cloth. The cryo
blasting can improve the results, but the surfaces may become wet
due to condensation of humidity after extensive surface cooling by
the cryo blasting. The samples have to be dried afterwards
