Abstract
An electrically insulated needle tip is provided for forming an electrospray from a solution containing a solute sample. The insulated needle tip is positioned between an upstream electrode and a downstream counterelectrode. The solution passes through the needle, emerges from the insulated tip and is converted to an electrospray under the influence of an electric field generated between the electrode and the counterelectrode.
