A new microfluidic concept for quantitative whole-column fraction collection of electrophoretically separated zones was developed. The prototype device, fabricated on a polycarbonate disk by injection molding, integrated electrophoretic separation channels with fraction collection reservoirs distributed along the separation channel. The microdevice was designed in a CD-like format to use the centrifugal force for moving the liquid in the microchannels. A serpentine shape of the separation channel was selected to create segments for quantitative whole-columnfraction collection. The operation was tested with visual monitoring of isotachophoretic separation and collection of cationic dyes.
