The nonlinear electromigration of analytes into confined spaces
Zhen Chen, Sandip Ghosal
We consider the problem of electromigration of a sample ion (analyte) within a uniform background electrolyte when the confining channel undergoes a sudden contraction. One example…
Strongly nonlinear waves in capillary electrophoresis
Zhen Chen, Sandip Ghosal
In capillary electrophoresis, sample ions migrate along a micro-capillary filled with a background electrolyte under the influence of an applied electric field. If the sample conce…
A nonlinear equation for ionic diffusion in a strong binary electrolyte
Sandip Ghosal, Zhen Chen
The problem of the one dimensional electro-diffusion of ions in a strong binary electrolyte is considered. In such a system the solute dissociates completely into two species of io…
Electromigration dispersion in a capillary in the presence of electro-osmotic flow
S. Ghosal, Z. Chen
The differential migration of ions in an applied electric field is the basis for separation of chemical species by capillary electrophoresis. Axial diffusion of the concentration p…
Nonlinear waves in capillary electrophoresis
Sandip Ghosal, Zhen Chen
Electrophoretic separation of a mixture of chemical species is a fundamental technique of great usefulness in biology, health care and forensics. In capillary electrophoresis the s…
Electromigration dispersion in Capillary Electrophoresis
Zhen Chen, Sandip Ghosal
In a previous paper (S. Ghosal and Z. Chen Bull. Math. Biol. 2010, vol. 72, pg. 2047) it was shown that the evolution of the solute concentration in capillary electrophoresis is de…
