  • Atmospheric pressure plasma apparatus
    Patent number: 8110990
    Abstract: Disclosed is an atmospheric pressure plasma apparatus for enhancing and or controlling the dissociation of a secondary gas by converting a source gas into a plasma state at atmospheric pressure and controlling the interaction between that plasma and the secondary gas using porous metal, and ceramic tubes to create a path having controllable isolation from the region where plasma is generated.
