electrophoretic mobility, μ

The observed rate of migration of a component (v) divided by electric field strength (E) in a given medium.
  1. 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).
  2. In a solid support medium, only apparent values can be determined.
