Electrophoretic mobility (Given viscosity of medium, net charge and Stokes radius of analyte)

Formula

Electrophoretic mobility (Given viscosity of medium, net charge and Stokes radius of analyte) formula
mup
the electrophoretic mobility
eta
the viscosity of the medium
z
the net charge of the analyte
r
the Stokes radius of the analyte

Formula description

The electrophoretic mobility is proportional to the ionic charge of a sample and inversely proportional to any frictional forces present in the buffer. When two species in a sample have different charges or experience different frictional forces, they will separate from one another as they migrate through a buffer solution.
