MQ, MilliQ water; Tap w, Tap water; FW, filtered pure water; ERWLV4, ERW at electrolysis level 4. +Mixed gas, H2, O2 and N2 mixed gas was bubbled through water to obtain DO and DH concentrations that are equal to those of ERWLV4. The pH was also adjusted using sodium hydrate. +H2Sat, H2 saturated water; +degas, Degassed; +autoclave, autoclaved. N.D.: Not detected.
