From: The bactericidal effect of an ionizer under low concentration of ozone
Effect of ion capture. a S. aureus was exposed to negative and positive ions with and without ion capture. The percent survival shown are the means of 5 replicates in each experiment. b The concentrations of ions measured with an ion meter during exposure to one ionizer with and without ion capture. c The concentrations of ozone measured with an ozone meter during exposure to one ionizer with and without ion capture. d The concentration of ozone was assessed from the discoloring of a solution of blue potassium indigotrisulfonate. Statistically significant differences are shown, ***p < 0.001
