The sum of electrophoretic velocity, \(\nu_{\rm{ep}}\), of an ion and the electroosmotic velocity, \(\nu _{\rm{eo}}\). \[\nu_{\rm{tot}} = \nu_{\rm{ep}}\,+\,\nu_{\rm{eo}}\] This quantity can be measured experimentally as the effective length of the capillary divided by the migration time (\(L_{\rm{eff}}/t_{\rm{m}}\)).
Notes:
- Depending on the signs and relative magnitudes of these velocities, the total velocity of an analyte can have either the same or the opposite direction to the electroosmotic velocity.
- The total velocity is the velocity of the ion measured as a displacement relative to the capillary wall divided by time.
