Abstract: Highlights: [•] CEC separations with one type of monolith in the reversed-phase, the normal-phase and a mixed retention mode. [•] Separations in the hydrophilic interaction liquid chromatography and in the ion-exchange mode are possible. [•] High efficiency routinely obtained with small analytes having a moderate retention factor. [•] Impact of solute functionality and mobile phase composition on plate height and peak asymmetry factor. [•] The contribution of axial diffusion can be approximated from molecular diffusion in an open channel. [Copyright &y& Elsevier]
