a mass spectrograph is used to measure the masses of ions, or to separate ions of different masses. in one design for such an instrument, ions with mass m and charge q are accelerated through a potential difference v. they then enter a uniform magnetic field that is perpendicular to their velocity, and are deflected in a semicircular path of radius r. a detector measures where the ions complete the semicircle and from this it is easy to calculate r.
