✦ Synopsis

As enantioselectivity, as expressed by the separation factor a , is not dependent on the applied voltage ( a = 1.02 k 0.005 for the phosphate), Chirasil-Dex columns are preferentially operated at high voltages.

4 Conclusion

To the best of our knowledge, this is the first time it has been shown that enantiomer separation may be achieved by electrochromatography employing a wall-coated chiral stationary phase. Further investigations will be directed toward testing Chirasil-Dex over a wider range of pH values and varying the polysiloxane backbone, as well as the nature of the cyclodextrin.
