ABSTRACT:
The present invention relates to an apparatus for producing ions from an electrospray assembly. The apparatus comprises an ionization chamber, an electrospray assembly, an isolating electrode, an isolated ionization region within the ionization chamber and optionally, a vacuum interface at a vacuum interface voltage and a vacuum chamber. Sample is introduced into the ionization chamber from an electrospray assembly and transported to an electric field region that is isolated from the electric field created by the electrospray assembly.
