If you have mastered the learning outcomes for Learning Module IV, congratulations! MEKC is a flexible separation technique with a host of applications . You have completed several self-guided exercises designed to expand your skill at performing qualitative and quantitative analyses using MEKC or capillary electrophoresis. This will assist you in devising separation strategies for future MEKC analyses that have not previously been performed. As you expand your use and knowledge of capillary electrophoresis, you will undoubtedly learn about, and hopefully apply, other modes of capillary electrophoresis such as capillary gel electrophoresis, affinity capillary electrophoresis, capillary isotachophoresis, and capillary electrochromatography.
