1. An ion deflector for modifying the path of travel of a beam of ions in a mass spectrometer, the deflector including an electric field inducer arranged so as to establish more than one electrostatic field capable of deflecting ions travelling substantially along a first intended path of travel so as to travel substantially along a second intended path of travel, the ion deflector comprising a deflection element arranged in such a manner so as to be positioned on or around the first intended path of travel so that the ions travel towards the deflection element before being deflected, wherein the deflection element is arranged with a voltage source so as to be capable of providing said deflection element with a required/desired bias voltage potential, if any, the electric field inducer comprising a chargeable component which includes more than one chargeable element, the chargeable component being positioned in generally opposed relation to the deflection element and spaced apart from both the first and second intended paths of travel, wherein each of the chargeable elements is arranged with a voltage source so that they each exhibit either a positive or negative bias voltage potential such that the beam of ions flows about a circumferential portion of the chargeable component through a space between the deflection element and the chargeable component. |
