Abstract
A method of mass and/or ion mobility spectrometry comprising: trapping electrons or reactant ions (3) within a reaction region with DC electric fields; conveying analyte ions (16) into a first side of the reaction region and through the reaction region such that they react with the electrons or reactant ions (3), and allowing the resulting ions (20) to exit the reaction region through a second side of the reaction region that is opposite the first side.
Claims21
A method of mass and/or ion mobility spectrometry comprising:
- trapping electrons or reactant ions within a reaction region with DC electric fields;
- conveying analyte ions into a first side of the reaction region and through the reaction region such that they react with the electrons or reactant ions, and allowing the resulting ions to exit the reaction region through a second side of the reaction region that is opposite the first side.
(canceled)
A mass and/or ion mobility spectrometer comprising:
- an ion source for generating analyte ions;
- an electrostatic trap for trapping electrons or reactant ions within a reaction region with DC electric fields;
- and
- at least one ion guiding device for guiding the analyte ions into a first side of the electrostatic trap such that the analyte ions pass through the reaction region inside the electrostatic trap, and wherein the electrostatic trap is configured to allow ions resulting from reactions between the analyte ions and the electrons or reactant ions to exit a second side of the electrostatic trap that is opposite the first side.
