	The program simulates 16 types of voltammograms with charge current
and random noise (i.e. DC, normal pulse, pseudo-derivative normal pulse, 
differential pulse, linear sweep, cyclic normal pulse, cyclic pseudo-
derivative normal pulse, cyclic differential pulse, and cyclic linear sweep 
voltammograms at both planar and spherical electrodes). The shape of normal 
pulse polarogram is equivalent to DC polarogram while the shape of pseudo-
derivative normal pulse polarogram is similar to differential pulse 
polarogram. But there is effect of the DC term on differential pulse 
voltammogram.
	The user can select polarography (voltammetry) methods (e.g. cyclic 
differential pulse, or cyclic linear sweep voltammetry at planar or 
spherical electrode), and input the number of species and individual 
species' parameters such as the rate constant ks, charge transfer 
coeffiecient alpha, number of electron n, concentration C, diffusion 
coeffiecient D, and standard potential E0. The user also can enter
the sweep range, potential step Es, potential scan rate v, pulse time tp, 
drop time td, area of electrode A, pulse amplitude, noise and baseline. 
The progrom displays voltammograms. It also outputs the number of peaks, 
the peak current and potential, and I-E data, which can be imported into 
other program (e.g. Lotus 123).
	It has been successfully applied to fit experimental polarograms
(voltammgrams) of In(III), Cd(II), Pb(II), Tl(I), Cr(III), Zn(II), and
binuclear copper complex in aqueous and non-aqueous media at mercury, 
solid metal and non-metal electrodes (specifically the dropping mercury,
hanging mercury drop, gold, platinum and glassy carbon electrodes) by
various electrochemical techniques (differential pulse, sqware wave, and 
pseudo-derivative normal pulse polargraphies) [1-5].
	It runs on IBM PC under MS-DOS, available from the author.
