This study demonstrates that the hydrodynamic phenomena taking place inside the capillary limits the frequency range of voltage pulses for stable single event electrospraying (SEE), when the meniscus/cone size is defined by the inner diameter of the nozzle. For the analysis of SEE, we used a one-dimensional model describing the displacement and oscillations of the liquid inside the nozzle. The frequency range of voltage pulses for stable SEE is related to the natural oscillation frequency of the fluid column inside the capillary.
