1)Migration
– movement of a charged
•particle in a
potential field – generally bad
•(important for
conductance & electrophoresis)
•In most cases
migration is undesirable and can be eliminated by adding a 100 fold excess
of an inert electrolyte (i.e., electrochemically inert – not
oxidized or reduced) Inert electrolyte does the migrating,
not the analyte
