This paper presents a model for Joule heating induced analyte dispersion in electrophoretic separation channels with a rectangular cross section. The model is in closed form and captures the effect of cross-sectional geometry. Three-dimensional numerical simulations are performed to satisfactorily verify the model, which can be used to accurately predict the performance of high speed electrophoretic separations.
