electro-osmotic hold-up time, $t eo$

in capillary electromigration

Time required for a liquid in a capillary to move due to electro-osmosis through the effective length of the capillary, $L eff$ . This time is usually measured as the migration time of a neutral compound, called an electro-osmotic flow marker which is assumed to have an electro-osmotic mobility that is negligible compared to that of the analyte.
