it depends on the specific ief method and apparatus.

for instance, 10000V is common for capillary ief.

4000V for gel ief may be the limiting voltage, it may actually run lower. i used to run with a 2000V power supply but never hit that voltage during the run (power and current had set limits, as well).

if the voltage is too high then you may experience arcing with concomitant burning of the gel.
