Abstract
The polarization (static or dynamic) of HD material requires very pure HD samples, with H2H2 and D2D2 impurities concentrations smaller than 0.1%. A new distillation apparatus equipped with a mass spectrometer has been built. It allows reaching such a level of purity and also measurement of the H2H2 and D2D2 residual concentrations down to 0.05%. The NMR spin–lattice relaxation times T1H and T1D have also been measured. The apparatus is described as well as the distillation method. T1H and T1D data as a function of [H2][H2] and [D2][D2] concentrations are given, at 0.85 T and 1.8 K.
