This result corroborates the relation among induced EOF, concentration polarization, and limiting-current behavior.

This approach was effective under both normal and reverse EOF situations and adapted to real samples.

The EOF pump was successfully used as a means of introducing samples into a capillary system.

The model demonstrates that spatial variations of electrical double layer properties induce the nanoscale vortices and nonlinear EOF.

A stronger EOF in the presence of LiCl is found to originate essentially in a stronger anionic selectivity of the pore.
