Abstract : Several volatile liquids were investigated to determine if they could be atomized electrically. Liquids studied included distilled water, ionically doped water (H2SO4 in H2O), and liquid nitrogen. The liquids were forced under pressure through small metal capillary tubes held at high positive potentials with respect to a nearby ground plate. Liquid nitrogen was studied at atmospheric pressure and in vacuo; water was investigated only in vacuo. Particles sprayed from the capillary tubes were monitored with charged particle detectors to measure any net electrical charge. Resulting sprayed particles in all cases had net charge insufficient to be detected above background noise. The lack of charge on the sprayed particles can be explained by analysis of the key times required for ion separation in the liquid versus the time the ions spend in the electric field (a study of liquid velocity versus ion mobility). Limitations of volatile liquids sprayed at near atmospheric pressures are not so severe; under certain conditions the liquids examined might be electrically sprayed in a controlled manner. (Author)
