Calculation of retention factors for charged solutes in capillary electrochromatography

An equation describing the capillary electrochromatographic (CEC) retention factor is derived using the fundamental chromatographic concept of retention factor. This retention equation couples both the chromatographic retention factor and the electrophoretic velocity factor, which can explain well the charged solute retention in CEC. The known CEC retention expressions are compared. A simple experimental method for obtaining the CEC retention factors for charged solutes is demonstrated.
