An asymptotic solution to the partial differential equation governing solute behavior in the continuous flow electrophoresis device is combined with solutions for the convective, electrophoretic and electroosmotic velocities in the chamber under nonisothermal operating conditions. The results illustrate the effect of temperature gradients on the net dispersion of solute in continuous flow electrophoresis. Three modes of operation are tested for this chamber: the convective velocity is in the same direction as gravity, the convective velocity is in the direction opposite to gravity and the effect of gravity is negligible.
