Abstract
Capillary electrophoresis is effected by introducing into a capillary a buffer solution a zwitterion composition comprised of substantially equal numbers of positive and negative charges when the negative charges are desired from sulfonate or sulfate groups and the positive charges are derived from quaternary amines, quaternary phosphines or quanternary arsines. A sample is introduced into the capillary and an electric field is established through the capillary to cause the sample to migrate through the capillary.
