The role of silver nitrate as additive in non-aqueous capillary electrophoresis

In this study, effect of use of silver nitrate as additive on non-aqueous capillary electrophoresis (NACE) separations of some structurally related compounds belonging to antidepressants, neuroleptics or sulfonamides, was examined. The presence of silver nitrate was found to enhance these NACE separations. The use of silver nitrate provided a successful method of improving the separations of antidepressants, neuroleptics and sulfonamides. The use of cyanomethyl-calix({[}4])arene (CMCX({[}4])) in the presence of silver nitrate for the separation of sulfonamides has significantly affected the separation.
