摘要
The invention relates to a method and a mass spectrometer for mass spectroscopic or mass spectrometric investigation of particles. The particles are separated in a separating system in accordance with their different masses. In order to reduce detection errors due to scattered particles, there is arranged upstream of a detecting device a correction device which builds up a braking potential in order to suppress particles having an energy loss due to scattering. The invention provides a further, preferably combined correction, by means of which the particles are selected as a function of their direction of motion. For this purpose, the mass spectrometer according to the invention preferably has at least one braking electrode and one quadrupole lens.
