Polar descriptions Software POLAROGRAPH. com is virtual polarograph & general electrochemical simulator with data analysis. It analytically & digitally simulates voltammograms on virtually any mechanism at over 10 electrode geometries in over 10 techniques . It also simulates over 20 effect factors e. g. charge current resistance noise preconcentration time & potential convection pH the reactant & product numbers etc. User can type in his mechanism with any symbol. It also includes over 200 theoretical equations. It plots & analyses any x-y data for peak location peak height peak width semi-derivative derivative integral semi-integral convolution deconvolution curve fitting & separating overlapped peaks & background current It shows tip when the user put mouse cursor over a label. The program can separate overlapped voltammograms into individuals & extract real peak from voltammogram with noise & baseline. It outputs the theoretical peak values the peak current & potential & current-potential data which can be imported into other program . User can copy-and-paste the voltammogram into his document. It has been successfully applied to fit experhymental polarograms of In Cd Pb Tl Cr Zn & binuclear copper complex in aqueous & non-aqueous media at mercury solid metal & non-metal electrodes by various electrochemical techniques .
