Abstract
A multimode ionization source includes an electrospray ionization source for providing a charged aerosol, an atmospheric pressure ionization source downstream from the electrospray ionization source for further ionizing said charged aerosol, and a mode separator, or mask, situated so as to separate a portion of the charged aerosol and prevent the portion from being exposed to the atmospheric pressure ionization source.

1-19. (canceled)
A multimode ionization source, comprising:
- (a) an electrospray ionization source for providing a charged aerosol along a central axis;
- (b) a mode separator for separating the charged aerosol into first and second portions;
- (c) a second atmospheric pressure ionization source situated downstream from the electrospray ionization source for further ionizing the second portion of the charged aerosol;
- (d) a first conduit having an orifice for receiving the first portion of the charged aerosol;
- and
- (e) a second conduit adjacent to the downstream atmospheric pressure ionization source having an orifice for receiving the second portion of the charged aerosol further ionized by the second atmospheric pressure ionization source.
