Rapid, Quantitative separation of metals by DYNA-CATH mercury cathode This modern apparatus makes mercury cathode a practical analytical tool. DynaCath does a fast, complete job in separation of metals. A novel magnetic circuit causes the electrolyte and mercury to move in opposite directions, providing counter-current stirring. The ferromagnetic metals formed at the interface are drawn beneath the mercury surface, providing a continuously clean surface and preventing resolution of deposited metals. Ask for Bulletin 220-D.
