If you have mastered the learning outcomes for Learning Module II, congratulations! Capillary electrophoresis is a flexible separation technique that requires some experience for developing methods that are providing the efficiency and/or selectivity requisite for a particular application. Learning Module III is a self-guided exercise designed to teach you the basics of a different mode of electrophoresis based on secondary separation equilibria: micellar electrokinetic capillary chromatography. This will assist you in devising separation strategies for future capillary electrophoresis analyses. The procedures you have mastered in Learning Module II will be required to further refine your laboratory skills in the third Module.
