Moving-boundary electrophoresis equation

Using the derived equations It Is possible to calculate all dynamic parameters of analytical importance [3]. Moreover, the model considerations can be extended to moving boundary electrophoresis as well as zone electrophoresis. Due to the fact that dlffuslonal effects play no role In the steady-state of isotachophoresls and It does e.g. In zone electrophoresis, the zone-characteristics will be different. 

The moving boundary spreading in the electrophoresis of protein is usually measured in terms of the refractive index gradient dn/dr, where n is the refractive index. The results are often recorded as shown in Figure 13.12. The formation of the boundary, its spreading, and its separation (if any) are functions of diffusion. The equation of the moving boundary is given in the form... 

The hydrodynamics of fluid flow in micro-particle electrophoresis chambers are described by solutions to the Navier-Stokes equation for steady laminar fluid flow (equation (19.1)) with boundary values defined by the chamber geometry. When considering the dimensions of an experimental chamber compared to the thickness of the double-layer (mm to nm), fluid flow at the surface would appear to move at a constant velocity. In other...
