  • Title: Microdevice for separation and quantitative fraction collection.
    Author: Spesný M, Foret F.
    Journal: Electrophoresis; 2003 Nov; 24(21):3745-7. PubMed ID: 14613200.
    Abstract:
    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-column fraction collection. The operation was tested with visual monitoring of isotachophoretic separation and collection of cationic dyes.
