Polar

Polar analytically and digitally simulates voltammograms (polarograms) on about 20 mechanisms at 8 electrode geometries (planar, spherical, semi-spherical, cylindrical, semi-cylindrical, microdisc, thin film, and rotating electrodes) in over 5 techniques (linear sweep and CV, DC, normal pulse, differential pulse, and square wave voltammetries). It outputs current, resistance, conductivity and surface concentration. It also simulates effects of charge current, resistance, noise, electrolyte, stripping time, strippingpotential, etc.

Polar analyses any ASCII x-y data for detecting peak location, peak value, semi-derivative, derivative, integral, semi-integral, curve fitting, and separating overlapped peaks.

It shows a tip when the user put mouse cursor over a label. It can separate overlapped voltammograms into individuals, and extract real peaks from voltammogram with noise and baseline. Users can compare by the theoretical peak values, analytically and digitally simulation, and choose to extract which kinetic parameters. Its data can be imported into other program (e.g. MS Excel).

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).
