Abstract
The electrospray generator system described herein uses a soft X-ray source instead of a radioactive source to generate bipolar ions for the neutralization of the initially charged particles. In one example, the soft X-ray source is directed at an orifice from which the charged particles emanate, thereby allowing the neutralization of the particles to happen faster than in prior art configurations and, in some instances, even neutralization occurring immediately on a droplet before it passes through the electrospray orifice.
