The use of non-equilibrium, or “cold”, plasma is a very energy efficient way to  modify surface properties and remove surface contamination as well as react gas phase impurities.
aurora holds expertise in the generation and application “cold” plasma particularly in the fields of surface modification and gas processing.

By channelling energy into heating the chemically active free electrons, rather than wastefully heating the bulk gas, non-equilibrium plasma is a particularly energy efficient way of delivering the well known benefits of plasma processing. In addition, operation at, or about, ambient pressure and temperature means the expense of often bulky vacuum equipment can be avoided. “Cold” plasma has applications in:-

     Surface processing - removal of surface contamination and the modification of surface properties through exposure to plasma.

     Sterilisation - in situ generation of biocidal species through the interaction of plasma with biologically active material.

     Pollution control - a “green” alternative to conventional, energy hungry, burner/scrubber combination systems used to treat effluent gases.
