Overview

Simulation and experimental study reveals a semiempirical correction factor for ultramicroelectrode edge effects, indicating improved accuracy for stochastic electrochemical particle sizing.

Key Points

Develop an analytical and semiempirical framework to compensate for diffusional edge effects at ultramicroelectrodes during stochastic blocking collision experiments for precise particle sizing.
Measured current-step reductions from stochastic blocking collisions using two fixed sizes of polystyrene beads across varied ultramicroelectrode diameters.
Coupled experimental collision measurements with numerical simulations to characterize diffusional flux variations between electrode edges and centers.
Derived and evaluated a semiempirical edge-flux correction factor across diverse electrode and particle size regimes.
Identified critical electrode-to-particle size ratios where elevated diffusional flux at electrode perimeters significantly skews collision current steps.
Demonstrated that applying the semiempirical edge-flux correction factor substantially reduces error in estimated particle diameters compared to uncorrected analytical models.
