## Abstract Solute migration in capillary electrophoresis is the sum of the molecularly specific electrophoretic mobility and the electricβfieldβinduced solvent flow (electroosmosis). This solvent flow is an important component of capillary electrophoresis and has been linked to resolution and auto

## Abstract The effect of the superposition of electroosmotic flow and pressureinduced hydrodynamic counterflow on efficiency has been investigated for different capillary electrophoretic systems. Results are shown for 50 and 75 ΞΌm internal diameter capillaries at several voltage and counterpressur
Nonaqueous capillary electrophoresis (NACE) is a powerful tool for the analysis of surface-active substances, which represent a broad class of analytes containing cationic and anionic species, such as surfactants, phosphoric acid esters, and amines. In order to conduct an efficient method developmen
A method for controlling the electroosmotic flow EOF in a capillary is reported using radial electric fields which vary along the length of the separation capillary. The magnitude of the control is compared to the control achieved using radial fields which remain constant along the length of the cap
