Characterization of a novel VHF-CCP for sterilization and decontamination of medical instruments
Résumé
A novel VHF-CCP was developed for sterilization and decontamination of medical instruments. The sterilization process is a two-step process: at first, an evaporated liquid is set into the chamber, e.g. water. Afterwards, plasma is ignited either solely with the remaining water vapor or with hydrogen gas in addition. As a "proof-of-concept", microbiological investigations are presented. To mimic worst case conditions, microbiological investigations were carried out in a so called "process challenging device", a metal box with small slits (0.3 mm). Besides, the condensation process was investigated with a high-speed camera in combination with a distance microscope objective.
