Gradient LC analysis of herbicides and polyaromatic hydrocarbons by isocratic Capillary Electrochromatography
Abstract:
Capillary Electrochromatography (CEC) combines the separation principle of HPLC (partitioning between mobile and stationary phases) with the high efficiency of
capillary electroseparation
methods. In CEC the electroosmotic flow (EOF) inherent in
capillary electrophoretic separations is used to transport solute and mobile phase through a packed capillary column. The properties of the EOF provides higher efficiencies than can be realized with L.C. This can be
sufficient to allow the transfer of methods conventionally
performed by gradient LC to be performed by isocratic CEC.
