Abstract
Articles which it is intended to sterilize are placed into a confined volume and are subjected to neutral species of an electrical discharge while maintaining the volume glowless and substantially field free by interposing a barrier between the articles and the discharge, the barrier being transparent to neutral species and opaque to charged species emanating from the discharge.
Claims34
A method for sterilizing a surface of an object, comprising:
- locating said object within a confined space and providing a plasma within a portion of said confined space, said plasma including both charged and electrically neutral active species;
- maintaining a barrier between said object and said plasma within said confined space, said barrier constituting means for substantially isolating said object from said charged species while permitting contact of said surface by a portion of said neutral species;
- and
- maintaining said plasma within said portion of said confined space for a sufficient duration to effect sterilization of said surface at a temperature below that which would be detrimental to said surface.
