Abstract
Single stage separation systems have limitations in resolving multicomponent
mixtures and two-dimensional systems have higher peak capacities. A valveless
interface for hyphenating Reversed-phase Microchromatography (-RPLC)
and Capillary Zone Electrophoresis (CZE) -highly orthogonal separation
methods- is presented, which main innovation is a third electrode.
Design and operation of the interface as well as some preliminary results
obtained by combining FIA and -RPLC with CZE are shown.
Key words: Two dimensional systems / micro-LC / CZE / valveless interface.
