Summary

The dual separation mechanism exhibited by capillary electrochromatography is demonstrated by the simultaneous separation of sulfonamides as charged and neutral species over a pH range of 2.5 to 6.9. The neutral sulfonamides were separated according to the difference in their hydrophobicities while charged components were separated by the differences in their electrophoretic mobilities. The limitation of capillary electrochromatography for acidic components was also examined.
