CAPILLARY ELECTROPHORETIC SYSTEM FOR SEPARATION OF SAMPLES CONTAINING BOTH POSITIVELY AND NEGATIVELY CHARGED COMPONENTS

摘要

A sample having both positively and negatively charged components may be separated during the same run by injecting a plug of sample at both ends of the capillary and applying an electric field in the capillary, where there is insufficient electroosmotic flow in the capillary to reverse sample migration direction, such as in the case of a gel-filled column.
