Abstract

In this study a new developed apparatus using CAP is presented as an alternative for the sterilization of sensitive materials. The apparatus uses the plasma afterglow generated by a surface micro-discharge (SMD) plasma source and functions with a circulating gas flow and variable treatment volumes. The afterglow components were analyzed using an UV absorption spectrometer and a FTIR spectrometer. We present the results of the spectroscopic afterglow investigations in dependence of different plasma conditions as well as the inactivation efficacy of the apparatus.
