Abstract
AbstractIn order to study the impact of different gas compositions on the bactericidal efficiency of cold atmospheric plasma jets, a device with a controlled atmosphere is built. Various mixtures of argon and helium with air are studied regarding their sterilizing effect onEscherichia coliin solution. Bacteria reduction rates react fundamentally different on addition of air in both gases. In case of helium, a distinct maximum for small admixtures is observed.Several diagnostic techniques were applied to the plasma. Stronger formation of peroxynitrous acid due to higher concentrations of hydrogen peroxide and nitrite is found to be responsible for the observed trends and differences. The presented findings are important for the development of efficient treatment devices.
