Method and arrangement for generating an atmospheric pressure glow discharge plasma (APG)

摘要

The method involves arranging electrodes (4, 5) to define a discharge space for forming atmospheric pressure glow discharge plasma (7). The electrodes are connected to an AC power supply (8) for applying an AC voltage to the electrodes. The AC voltage has a frequency of 50 kilohertz, and a gaseous substance (6) that is provided in the space has a group comprising argon, nitrogen and air. An independent claim is also included for an arrangement for generating atmospheric pressure glow discharge plasma.
