【Abstract】 A new type of multi - channel electrochemical detection technology for capillary electrophoresis is des-cribed. The amperometric detector and the conductometric detector are connected in parallel to the same capillary electrophoresis system. Under the same buffer circumstance, the signals are collected by the amperometric detector and the conductometric detector at the same time using the same Pt wire working electrode and the same counter electrode. The whole system possesses the combination advantages of the two electrochemical detectors and was applied for the determination of some alkaline metal ions and phenols with satisfactory results.更多还原
