Abstract

See full text

The invention relates to a tandem mass spectrometer comprising an ionization source that can produce ions; a mass analyzer comprising an ion trap arranged in such a way as to receive ions from the ion source and a detector that can detect ions leaving the ion trap according to the mass to charge (m/z) ratio thereof; ion activation means for activating ions that can fragment at least some of the ions trapped in the ion trap; and coupling means arranged between the ion trap and said ion activation means. According to the invention, the ion activation means consists of a glow discharge lamp that can generate a light beam oriented towards the ion trap, said light beam being electromagnetic radiation in the vacuum ultraviolet wavelength range with photon energies of between 8 eV and 41 eV in such a way as to fragment at least some of the ions trapped in the ion trap.
