THE EFFECT OF A CROSSED MAGNETIC FIELD ON CAPILLARY ELECTROPHORESIS

A powerful permanent magnet which can perform a uniform 10 KG magnetic field was directed perpendicular to the applied electric field in a Capillary Electrophoresis (CE) system. It was found that the current passing through the capillary was decreased due to application of a magnetic field. The electroosmotic flow and electrophoretic mobility of ionic solutes were also observed to be affected and slowed down by this new external field.
