electrophoretic mobility, \(\mu\)

The observed @R05154@ of a component (\(v\)) divided by electric field strength (\(E\)) in a given medium.
  1. Mobilities are sometimes expressed with a negative sign, because @M03920@ 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.
