Abstract (en)
A system for separating certain ions from an ion beam in a mass spectrometer. A magnetic or electrostatic field is applied at an angle to the ion beam, causing the ions to disperse according to their mass to charge ratio. The ions are dispersed enough to allow certain ions to be blocked and removed from the beam using a physical stop. A subsequent plurality of fields is then applied to reform the beam and adjust its direction and dispersion. The system can be used to remove carrier gas ions from an ion beam in a gas chromatography-mass spectroscopy instrument. <IMAGE>
