Digital simulation of differential pulse polarography with incremental time change

Explicit finite difference simulations of TAST, normal pulse and differential pulse polarography for the reversible case have been developed for conserving computer time. The method involves changing the time increment during the simulation. The results are shown to conform to accepted theory and include sphericity and the DME compression of the diffusion layer due to the drop expansion in area. The DC faradaic distortion of differential pulse is also studied. The simulation gives a factor of five savings in computer time over simulators of the standard type.
