total velocity of the analyte, ν tot

in capillary electrophoresis
The sum of electrophoretic velocity, ν ep, of an ion and the electroosmotic velocity, ν eo.
ν tot = ν ep + ν eo
This quantity can be measured experimentally as the effective length of the capillary divided by the migration time (L eff t m).
  1. 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 electro- osmotic velocity.
  2. The total velocity is the velocity of the ion measured as a displacement relative to the capillary wall divided by time.
