Capillary electrophoresis (CE) is a useful method for rapid separations of metal cations. Under ideal conditions, CE can provide
complete separation of the trivalent lanthanides in less than 10 min. Simple organic ligands must be included in the electrolyte
matrix to achieve good resolution between the cations. In this paper, we demonstrate how to use complexation constants from
the literature to design separation protocols for the trivalent f-elements.
