DEVICE AND METHOD FOR GENERATING REACTIVE SPECIES BY MEANS OF PLASMA AT ATMOSPHERIC PRESSURE.

摘要

An atmospheric pressure plasma generator device (1), in particular an induction plasma torch for the treatment of substrates of biological and in general heat-sensitive material, comprises: a plasma generating chamber (3), connected to an electric generator (4) designed to create an electromagnetic field in the plasma generating chamber (3) and connected to a source of inert gas (6) for receiving a flux of inert gas (6), and a plasma cooling chamber (7), located downstream of the plasma generating chamber (3) and configured to cool the plasma and convey it onto a substrate (2) to be treated; the plasma generating chamber (3) is also connected to a source of reactive gas (9) for receiving a flux of reactive gas (9) in order to mix the inert gas (6) and the reactive gas (9) in the plasma generating chamber (3).
