Abstract
The invention is related to a corona plasma-generating device (1), comprising at least one first plasma-generating section (A), wherein at least one first plasma (2) is generated; and at least one second plasma-generating section (B), wherein at least one second plasma (3) is generated; wherein at a given point of time said first and said second plasmas (2,3) are of different polarity. The device is especially suitable for the sterililzation of a gaseous medium such as biologically or otherwise contaminated air.

1-30. (canceled)
A plasma-generating device, comprising
- at least one first plasma-generating section, wherein at least one first plasma is generated;
- and
- at least one second plasma-generating section, wherein at least one second plasma is generated;
- wherein at a given point of time said first and said second plasmas are of different polarity.
A plasma-generating device, comprising
- at least one plasma-generating section, wherein a plasma is generated between electrodes;
- a conveyor for controlling the conveyance-speed of a gaseous medium through the plasma-generating section;
- an AC power supply which is connected to said electrodes to generate alternating plasmas of different polarity;
- wherein the power supply operates with a frequency that is adapted to the conveyance speed of the gaseous medium suchlike that substantially all of the gaseous medium is subjected to both of said plasmas of different polarity at least once.
A method of treating a gaseous medium with a plasma-derived reactive species,
- said method comprising steps of:
- generating at least one first plasma;
- generating at least one second plasma;
- wherein said first and said second plasmas are of different polarity;
- contacting the gaseous medium with said first and said second plasma.
A method of sterilizing a gaseous medium with a plasma-derived reactive species,
- said method comprising steps of:
- generating at least one first plasma;
- generating at least one second plasma;
- wherein said first and said second plasmas are of different polarity;
- contacting the gaseous medium with said first and said second plasma.
