The sum of
electrophoretic velocity,
, of an ion and the electroosmotic velocity,
.
This quantity can be measured experimentally as the effective
length of the capillary divided by the
migration time
(
).
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 electro-
osmotic velocity.
-
The total velocity is the velocity of the ion measured as
a displacement relative to the capillary wall divided by
time.
