Abstract: Very rapid capillary electrochromatography (CEC) mode enantiomer separations of propranolol using short super-porous monolithic molecularly imprinted polymers (MIPs) were studied. MIP stationary phases were synthesised by an in situ photo- initiated polymerisation reaction. The effect of electrolyte composition on the enantiomer separation and the stability of the MIP-column performance was investigated. The optimised MIP- CEC separation system was able to resolve the enantiomers of propranolol in less than 1 min. (C) 2001 Elsevier Science B.V.
