Universal Joule Heating Model in Electrophoretic Separation Microchips
Y. Wang, Q. Lin and T. Mukherjee
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.
