Consider a capillary electrophoresis experiment conducted near pH9, at which the electroosmotic flow is stronger than the electrophoretic flow. (a) Draw a picture of the capillary, showing the placement of the anode, cathode, injector, and detector. Show the direction of electroosmotic flow and the direction of electrophoretic flow of a cation and an anion. Show the direction of net flow. (b) Using Table 15-1, explain why Clhas a shorter migration time than I. Predict whether Brwill have a shorter migration time than Clor a greater migration time than I. (c) Why is the mobility of Igreater than that of Cl? Consider a capillary electrophoresis experiment conducted near pH9, at which the electroosmotic flow is stronger than the electrophoretic flow.
