Abstract:
Among other things, we describe methods and apparatus for the ionization of target molecular analytes of interest, e.g., for use in mass spectrometry. In some implementations, a thin molecular stream is emitted in either single or a split mode and encounters both an electron-impact ion source and trochoidal electron monochromator placed sequentially or coincidentally. The first ion source emits high-energy electrons (˜70 eV) to generate characteristic positively-charged mass fragment spectra while the second source emits low-energy electrons in a narrow bandwidth to generate negative molecular ions or other ions via electron capture ionization. The dual ion source may be coupled to analytical instruments such as a gas chromatograph and to any number of mass analyzers such as a polarity switching quadrupole mass analyzer or to multiple mass analyzers.

Claim (Index 3):
The apparatus of  claim 1 , wherein an electrostatic deflector separates ions of opposite charge before mass analysis by multiple mass analyzers, enabling simultaneous detection of positive and negative ions without the need for polarity switching.
