Abstract: The invention relates to an appliance (18) for at least partially disinfecting/sterilising a contaminated surface (21), wherein the appliance (18) comprises an integrated plasma source for at least partially disinfecting/sterilising the surface by generating a non-thermal atmospheric plasma on the surface thereby reducing the concentration of pathogenic germs on the surface.

Abstract: The invention relates to an appliance (18), particularly kitchen appliance or laboratory table, for at least partially disinfecting/sterilising a contaminated surface (21), wherein the appliance (18) comprises an integrated plasma source for at least partially disinfecting/sterilising the surface by generating a non-thermal atmospheric plasma on the surface thereby reducing the concentration of pathogenic germs on the surface.

Abstract: A coaxial microwave plasma torch, comprising, an outside conductor (1) formed in a cylindrical shape, a cylindrical electric discharge tube (3) fixedly inserted into an axial hole (2) formed in the outside conductor on one end face (4) side, and a coaxial cable (6) having one end fitted to the other end face of the outside conductor. An antenna (9) electrically connected to an inside conductor (8) is fitted to the one end of the coaxial cable and extended into the electric discharge tube through a through-hole (11) axially passed through between the other end face (5) of the outside conductor and the bottom face of the axial hole. The outside conductor (7) of the coaxial cable is electrically connected to the outside conductor, and a gas inlet pipeline (13) supplying a gas into the electric discharge tube is fitted in the outside conductor.

Abstract: A microwave plasma generator in which the generating amount of radicals can be regulated easily with higher reaction efficiency while reducing gas consumption. The microwave plasma generator comprises an outer conductor (2), an inner conductor (3) arranged in the internal space (4) of the outer conductor, a discharge tube (7) having a double tube structure consisting of an inner tube (5) and an outer tube (6) and penetrating the outer and inner conductors in the axial direction, and a cavity (1) having a means for adjusting the position of the inner tube to the outer tube in the axial direction in the discharge tube.

Abstract: A method of low temperature sterilization that with the use of a compact simple apparatus, is capable of safe, unfailing sterilization. There is provided an apparatus comprising gas cylinder (gas supply source)(8), high energy particle generation part (1-3) capable of generating a gas of temperature nonequilibrium condition containing high energy particles through exciting of the gas supplied from the gas cylinder (8) and gas blow part (4) capable of jetting the gas of temperature nonequilibrium condition generated by the high energy particle generation part (1-3) over pathogenic microbes positioned outside.
