摘要：

A novel modified electrode dispersed with ultrafine platinum particles on the surface of a 30-mu m carbon fibre microelectrode was investigated as an amperometric detector in capillary zone electrophoresis (CEEC) for determining hydrazines. The unique characteristic of the Pt particle-modified carbon fibre microelectrode is its excellent stability. Hydrazines were separated and detected by CEEC with the modified microelectrode with detection limits down to the femtomole level.
