  • Patent number: 10039849
    Abstract: The invention relates to a method and to a device for quickly decontaminating and sterilizing preferably thermolabile goods using a plasma gas that is preferably generated from air as a process gas, with the subsequent humidification of said plasma gas with water. The method comprises the following steps: generating a plasma from air as the process gas, which forms reactive nitrogen and oxygen species; oxidizing NO to form NO2 at temperatures below 400° C. so that a plasma-activated gas mixture forms having an NO2 content of at least 0.3%; bringing said plasma-activated gas mixture in contact with water in one or more of the states of aggregation thereof; bringing the latter gas mixture in contact with the objects to be decontaminated or sterilized.
    Type: Grant
    Filed: April 14, 2017
    Date of Patent: August 7, 2018
    Assignee: LEIBNIZ-INSTITUT FUER PLASMAFORSCHUNG UND TECHNOLOGIE E. V., INP GREIFSWALD
    Inventors: Udo Krohmann, Joerg Ehlbeck, Torsten Neumann, Uta Schnabel, Mathias Andrasch, Wolfram Lehmann, Klaus-Dieter Weltmann
