Figure 3: Influence of electrospray parameters on water-in-oil droplet size distribution.

(a) Comparison of nozzles with bigger (65 μm) and smaller (~4 μm) orifice diameters. Inset: The bigger nozzle exhibits an oscillating jet mode, which results in a polydisperse distribution with satellite droplets; the small nozzle produces highly monodisperse droplets because of its cone-jet mode. (b) Comparison of droplet sizes in oil/surfactant mixtures with different viscosities, prepared by changing the proportion of Tegosoft DEC while keeping the ABIL EM 90 and mineral oil at a fixed ratio. All observations were performed at a bias voltage of 50 V and a frequency of 100 Hz.
