Abstract
In a hybrid mass spectrometer, a high-energy collision chamber (8) is arranged in a field-free region (12) which, in the direction of travel of the ions, is located after the first stage (1 to 6). A lens arrangement (9) serves for decelerating daughter ions of different energies to a fixed energy, and preferably at the same time also for shaping the ion beam. Preferably, the hybrid mass spectrometer is of BEQQ configuration.
