Abstract
Official abstract text for this publication.
An apparatus and method of producing an atmospheric non-equilibrium plasma (ANEP) in a sealed container having a selected working gas and an object to be treated is described. A variety of working gas mixtures including air, O 2 , N 2 , CO 2 , He and Ar, in combination with a range of ionization gradients, voltages and ANEP column lengths was investigated so as to establish effective ranges of the variables using the sterilization of a sample as a measure of effectiveness. Certain combinations of working gas, voltage gradient, voltage and ANEP column length were found to have greater effectiveness. The approach may be used for food products, medical equipment, or other objects where treatment with reactive gas atmospheres is effective.
First claim
Opening claim text (preview).
What is claimed is: 1. A system for treating an object, comprising: an apparatus, configured to create an atmospheric non-equilibrium plasma (ANEP) in a gas in a storage volume sized and dimensioned to contain the object, the apparatus having: a pair of electrodes with a separation of greater than about 2.0 cm; and a voltage applied between the electrodes of greater than about 50 kV RMS. 2. The system of claim 1 , wherein the voltage applied between the…
