Electric-field induced phase transitions in capillary electrophoretic systems

The movement of particles in a capillary electrophoretic system under electroosmotic flow was modeled using Monte Carlo simulation with the Metropolis algorithm. Two different cases repulsive and attractive interactions between molecules were taken into consideration. Simulation done spin-like system, where nearest second closest neighbors considered two separate steps modeling study. A total 20 rates for both modeled. through is defined as current. At low interaction level molecules, regular obtained; on other hand, increasing current shows phase transition behavior. results also show that modular can be obtained separations by tuning ratio molecular electric field strength.
