Mathematical Approach by a Selectivity Model for Rationalization of pH- and Selector Concentration-Dependent Reversal of the Enantiomer Migration Order in Capillary Electrophoresis

摘要

A mistake has occurred in Table 1 in the eq 18 f eqn20 transition column for case III. As can be deduced fromnthe opposite selectivities at low pH/low[CD] and highnpH/low[CD], a pH dependent reversal of the enantiomernmigration order is observed at low [CD] so that thencorrect sign is a “+” in the eq 18 f eq 20 transitionncolumn. A corrected Table 1 is provided below. Thenextended table in the Supporting Information of thenpublication reflects the correct situation for all cases.
