O173100100023 During the experiment, nitrogen gas of natural isotopicO173100100024 composition and 99.9995% chemical purity was flowing O173100100025 through the windowless target cell with a flux of O173100100026 2 l/s. No recirculation was used, so the gas was O173100100027 discarded after one passage through the target.
