Introduction
Electrospraying is a method of liquid atomisation by electrical forces. The atomiser nozzle is usually made in the form of metal capillary, which is biased by a high voltage. The shear stress on the liquid surface, due to the established electric field, causes elongation of a jet and its disintegration into droplets. The droplets obtained by this method can be extremely small, in special cases down to nanometers. The advantage of the electrospray is that droplets are highly charged, up to a fraction of the Rayleigh limit. The Rayleigh limit is the magnitude of charge on a drop, which overcomes the surface tension force that leads to the drop fission. This charge is given by the following equation
