TL;DR: In this paper, the design of a novel cryogenic distillation column using the common McCabe-Thiele approach is described, and the system demonstrated a krypton reduction factor of 6.4$\cdot$10$^5$ with thermodynamic stability at process speeds above 3 kg/h.

TL;DR: In this paper, a cryogenic distillation column is integrated into the gas purification loop of the XENON100 detector for online radon removal, which enabled the authors to significantly reduce the constant background originating from radon emanation.

TL;DR: In this paper, a new distillation column to remove krypton out of xenon to a concentration of < 5 × 10−13 (0.5 ppt) was designed and tested at the Institut fur Kernphysik, Universitat Munster.

TL;DR: The separation characteristics under different operation conditions are determined for very low concentrations of krypton in xenon at the level of (83m)Kr/Xe = 1.9 ⋅ 10(-15), demonstrating that cryogenic distillation in this regime is working.
