title: Capillary zone electrophoresis in laboratory-made fluorinated ethylene propylene capillaries.
abstract: Capillaries made of fluorinated ethylene propylene (FEP) with an inner diameter of 50 microm have been employed in capillary zone electrophoresis with UV-Vis absorbance detection. The capillaries were made in the laboratory with a recently developed technique using fluoropolymer heat shrink/melt tubing and a tungsten wire as a template for the channel. An electroosmotic flow was obtained in the channels and it is shown that an FEP capillary is more effective for a cationic test solute than a fused-silica capillary. The compatibility of FEP capillaries with optical detection is evaluated briefly.
