electro-osmotic hold-up time, \(t_{\text{eo}}\)

in capillary electromigration
Time required for a liquid in a capillary to move due to @[email protected] through the effective length of the capillary, \(L_{\text{eff}}\). This time is usually measured as the @[email protected] of a neutral compound, called an electro-osmotic flow @[email protected] which is assumed to have an electro-osmotic @[email protected] that is negligible compared to that of the analyte.
