From: Qualitation and Quantitation on Microplasma Jet for Bacteria Inactivation

The quantitative analysis of ultraviolet radiation (a), charged particles (b), active species (c) and the inactivation effect with different length of ducts (d). (a) The logarithmic reduction of control group remains basically the same; (b) Inactivation effect of the separation group are almost the same as the control one; (c) There is not big difference between the control and separating group within 30 minutes before and the bacteria of both can almost be inactivated completely in 60 s; (d) Longer spreading distance of plasma leads to worse inactivation effect.
