ABSTRACT:
A source for producing a spray of drops and ions of a liquid material under the action of an electric field, comprises an emitting point in the shape of a cone with a rounded tip, the vertex angle of which is between thirty and forty degrees and which projects beyond a base structure by a distance of between some one and three millimeters, means for supplying a liquid material to be sprayed to the emitting point and a field generating electrode whereby there may be applied to the emitting point an electric field sufficient to disrupt the liquid material at the emitting point and provide a spray of liquid drops and ions, the emitting point being made of a material which is wetted by the liquid material and has a low solubility in the liquid material.
