Voltage programming was explored to accelerate the elution of late-Ε½ . eluting components in capillary electrochromatography CEC separations. Voltage programming was demonstrated to be an effective alternative to composition gradient programming with the separation of a mixture of polycyclic aromati

The operational parameters and factors which control the performance Ε½ . of capillary electrochromatography CEC using commercially available CEC instrumentation are evaluated and discussed. The CEC of neutral or ion-suppressed acidic analytes shows marked advantages such as increased column efficien
## Enhancement of electroosmotic flow in capillary electrochromatography A major impediment to enhancing the speed of separation in capillary electrochromatography (CEC) is the upper limit on the electroosmotic flow (EOF) velocity by the maximal zeta potential of the chromatographic surface. Here,
