Characteristics of atmospheric plasmas

  • The concentration and composition of reactive molecules produced in Cold Atmospheric Plasmas depends on the gases used, the gas flow, power applied, humidity level etc.

  • Reactive components are the product of a non-equilibrium plasma-gas phase chemistry, which is only poorly understood at present.

  • Chemical reaction networks with over 200 important reactions are being developed for our plasma devices*

  • Some of the major components (produced in air) are OH, *OH, H2O2, O, O3, NO, NOx, plus some ions, e.g. OH-, O+, O2+, N+, N2+ etc.
