Based on the McCabe-Thiele (M-T) method and the conservation of mass and energy. the PandaX-4T collaboration group designs an efficient cryogenic distillation system to reduce the mole fraction of krypton in commercial xenon from 5×10-7 to 1×10-14. Since the ultra-high purity xenon cryogenic distillation system has completed the offline purification operation. it is ne... https://www.mariameetsanna.com/product-category/spray-wax/
