The observed
rate of migration of a component
(
) divided by electric field strength
(
) in a given medium.
Notes:
-
Mobilities are sometimes expressed with a negative sign, because migration of the solutes or particles generally occurs in the direction opposite to the electrophoretic
field (which is taken as reference for that direction).
-
In a solid support medium, only apparent values can be determined.
