Software POLAROGRAPH.com (former Polar) is virtual polarograph and general electrochemical simulator. It analytically and digitally simulates voltammograms (polarograms) on virtually any mechanism at 9 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 also simulates effects of charge current, resistance, noise, electrolyte, stripping time, stripping potential, pH, etc.
