Study of a new chiral selector: Sodium arsenyl-(l)-(+) tartrate for capillary electrophoresis.
Sodium arsenyl-(l)-(+) tartrate (Na(2)[As(2)(+)-tart(2)].3H(2)O) was examined and evaluated as a chiral selector using capillary electrophoresis. This chiral selector showed enantioselective associations with many cationic analytes, including primary, secondary, and tertiary amines. Also, baseline separations of ruthenium(II) polypyridyl complexes were achieved within 10min. The effect of buffer type, chiral selector concentration, voltage applied, buffer concentration, buffer pH and organic modifier concentration were examined and optimized.
