H2O2 production at different water concentrations in the feed gas.
The feed gas of the capillary jet was (partially) routed through a cooled water-containing bubbler (in %) resulting in different concentrations of water (in ppm) in the feed gas. Potassium phosphate buffer (5 ml, 100 mM, pH 7) was treated for 10 min and the H2O2 concentration (in mM) was determined consecutively. Means and standard deviations represent three experiments shown. Standard deviations that are not visible were below 0.01 mM.
