    2.2.1 Removing air from Vessel 1 Once the system has been pressuris ed, tap A on Vessel 1 can be opened. It is possible to bubbled helium gas through the sample liqui d against the non-retu rn valve, V13. If this is required, first ensure th at valves V 5, V7 and V8 are closed. Open valves V10 and V6, finally opening tap B slowly in order to regula ...

    3 Example Experiment The paramagnetic signal in liquid n-hexane is difficult to observe because the muonium polarisation is found to decay on a microsecond time scale, which is further reduced by the presence of dissolved oxygen. A series of commi ssioning experim ents were carried out using n-hexane in order to gauge the ability of the liquid hand ...
