【Abstract】 The hardware design and software structure of a microcomputer-based multifunctional electrochemical analyzer is described. A high speed data acquisition system, a fast auto-ranging circuit and an analog switch control circuit are used in the analyzer The interrupted technique is adopted to improve resolution of overlapped voltammetric peaks. The analyzer can work either in potential-controlled mode or in current-controlled mode to perform multiscan potential stripping analysis. The functions of software are abundant and can be easily adapted according to practical experiment requirement The development and applications of interrupted square wave stripping technique and multiscan potential stripping technique are discussed.更多还原
