Are ionization energy and electron affinity the same phenomenon
For a particular CE experiment ueo = 1.3x10-8 m2 V-1 s-1. What will the migration time be for a neutral solute in a 52 cm capilllary under an applied field of 27 kV? In this experiment will you ever be able to detect an anion having uep = -1.6x10-8 m2V-1 s-1? Assuming the anion has a fixed charge, what could be altered so that the anion could be detected?
