[Display omitted] •Electrokinetic behavior of cylindrical nanopores subject to an extra pH-gradient is modeled.•ICR performance depends highly on the level of applied potential bias, and is optimum at a medium strong pH gradient.•Influence of PE layer thickness on ICR performance is important only i...
