Abstract: A new method named differential simple oscillographic voltammetry using pulse wave alternating current as polarization current is presented in this paper,Some advantages of using pulse wave are found.The method of adjusting E～t curve is first proposed in quantitative analysis. The results of determination for a series of drugs show that the method is very useful in actual analysis.

Key words: Oscillographic analysis, Differential simple oscillographic voltammetry, Pulse wave alternating current
