Abstract
Mass spectrometer having an ion source, acceleration means able to impart to the ions an energy essentially dependent on their electric charge, means for producing in a sector a magnetic field orthogonal to the plane of the trajectory of the ions in order to inwardly curve said trajectory and means for detecting the ions. At the inlet of the magnetic sector are provided electrostatic means able to modify the tangential velocity of the ions and consequently their energy, in such a way that ions with different masses can, at different times, follow the same inwardly curved trajectory in the magnetic sector.
