A mathematical model and computer code for simulat-ing electrokinetic fluid and sample manipulations in micro-fabricated fluidic devices (microchips) are described. The model accounts for mass transport mechanisms such as electrophoretic migration, bulk fluid motion due to elec-troosmosis, and diffusion. The interactive computer pro-gram implementing the model is capable of handling differ-ent channel geometries with various boundary conditions for the electric field distribution and sample concentration. Several microchip elements have been modeled and par-ticular attention has been paid to the electrokinetic injec-tion, one of the primary elements in microchip operation. The results obtained in the modeling have been compared with experimental data
