Abstract

The separation mechanism of high performance capillary electrophoresis was studied in light of chromatographic separation principle and by considering the effects of molecular diffusion

injection and power dissipation. The expression obtained for the height equivalent of a theoretical plate was compared with the experimental results. It was showed that the calculated results using the model were consistent with the experimental data. The model may provide the fundamentals for optimizing experimental conditions and scale up.
