Abstract:
An electrospray source of ions for an analyzer comprising:(a) a reservoir for containing a liquid; (b) a first manifold for containing a liquid, said manifold having a plurality of nozzles, each of said nozzles having a channel and a plurality of openings operatively connected to the channel, each of said nozzles having a second manifold between the channel and the openings of the nozzle, each of said second manifolds having a plurality of spaced tips that contain said openings; (c) a conduit connecting said reservoir to said first manifold so that liquid in said reservoir can flow from said reservoir to said openings; and (d) a counter electrode having an electrical potential difference between said counter electrode and said openings, said electrical potential difference and the size of said openings being sufficient to enable said liquid to be ejected from said openings in droplets and to enable ejection of ions from said droplets.
