Abstract (en)
[origin: EP2555225A1] The spectrometer has a mass analyzer comprising an ions trap (2) to receive ions from an ionization source (1) and a detecting unit to detect ions leaving the trap based on relative load mass of ions. An ions activation unit activates a part of the trapped ions. A luminescent gas-discharge lamp (4) of the activation unit generates a light beam directed toward the trap to fragment energies of photons ranging between 8-41 eV or for photoionization or photodetachment of the electrons guided to the trapped ions, where the beam is electromagnetic radiation in a field of vacuum UV. The luminescent gas-discharge lamp is designed as a helium discharge lamp, a neon discharge lamp, an argon discharge lamp or a krypton discharge lamp. An independent claim is also included for a tandem mass spectrometry method.
