a) b) c) Describe how an efficient separation of anions can be achieved using capillary zone electrophoresis (CZE). Two neutral compounds, A and B are succesfull separated by micellar electrokinetic chromatography (MEKC) using 15 mM borate buffer (pH 8) with 50 mM sodium dodecyl sulphate (SDS). i) The migration time of A and B are 8.1 and 13.0 min, respectively. Explain the hydrophobicity property of the compound based on the migration times obtained. ii) If SDS is added in a very low concentration (< 50 mM) into the system, explain the obtained separation. Give an advantage of MEKC over CZE.
