Capillary zone electrophoresis is a fully automated approach to electrophoresis that uses narrow-bore (10–100 μm) fused-silica capillaries as a separation chamber and online detection of analytes. The increased heat dissipation allows the delivery of high field strengths (100–500 V cm−1). The use of minute sample amounts and volumes and the very fast analysis times make it an attractive technique in modern bioanalysis.
