Polar 3.1 for Windows: electrochemical simulation and data analysis Dr Weiguang HUANG 124 Eastern Avenue, Kingsford, Sydney, NSW 2032, Australia Phone: 61 2 96620516, 0413 008 019 mailto:polarography@bigfoot.com, showing@bigfoot.com http://www.bigfoot.com/~polarography/ http://showing.home.ml.org It analytically and digitally simulates voltammograms and stripping voltammograms with charge current, resistance and noise on about 20 mechanisms at 8 electrode geometries (planar, spherical, semi-spherical, cylindrical, semi-cylindrical, microdisc, thin film, and rotating electrodes) in 5 techniques (linear sweep and CV, DC, normal pulse, differential pulse, and squre wave voltammetries), and outputs current, resitance, conductivity and surface concentration. Its data analysis include detecting peak area, current and potential, semi-derivative, derivative, intergral, semi-intergral, curve fitting, and separating overlapped peaks. It shows tip when the user put mouse cursor over a lable. The progrom can separate overlapped voltammograms into individuals, and extract real peak from voltammogram with noise and baseline. It outputs the theoretical peak values, the peak current and potential, and current-potential data, which can be imported into other program (e.g. MS Excel). User can copy-and-paste the voltammogram into his document. It has been successfully applied to fit experimental polarograms (voltammograms) 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]. It runs on IBM PC under Windows 95/98/NT, available from the author or download from my Web site. REFERENCES [1] W. Huang, T. Henderson, A.M. Bond and K.B.
