Current / voltage

Medium - (buffer/liquid) - with a precise pH value and a constant ionic strength.

 Analytes - A compound, which is to be detected or assayed in a given sample.

Electrophoretic resolution mainly can be change by manipulating current and buffer system.

The higher the buffer concentration, the more electric power is applied, resulting in higher heat (joule effect) development.

Smiling Effect, Venetian Blind Effect & Electroendosmosis reduces the efficiency of electrophoresis.

Slab gels can develop a “Smiling Effect” When in a gel more Joule heat is produced than can be dissipated, leads to the higher mobility of the ions in the center, resulting in an uneven distribution of the zones, These zones bend up at the two lateral sides, causing “smiling.”
