| Abstract: | The title effects can be eliminated if the slow bleeding of H2 from freshly reduced CuO-towers (often used as O2-getters in purifying N2 carrier gas) can be avoided, then H2–O2 titrations of Pt surfaces give consistent values from almost the first titration. Water injected at 25 °C also hardly affects the titer values.
