Abstract: Speciation of elements could provide valuable information for chemistry, environment,medicine and life science. As a new separation technique, capillary electrophoresis offers a number of important attributes including:high separation efficiency, short analysis time, and low sample consumption. The development in the elemental speciation analysis by capillary electrophoresis is reviewed with 56 references. Various CE separation modes (e.g., capillary zone electrophoresis, micellar electrokinetic capillary c...
