This paper presents an analytical Joule heating dispersion model for rectangular microchannels. The model holds in all convection-diffusion mass transfer regimes and captures the effects of cross-sectional shape and separation time on JH induced dispersion. The model is verified by three-dimensional numerical simulation and agrees with experimental data from microchip electrophoresis.
