A high speed mass spectrometer system capable of detecting in real-time multiple compounds in complex environments his system includes a continuous ionization source coupled to a quadrupole ion trap to store ions, to filter ions for detection, to resonantly excite the ion trajectories to cause them to dissociate for more detailed analysis. This system includes a dual ionization configuration to cover broad and disparate classes of compounds. A glow discharge source is used to attach electrons to molecules with high electrons affinity. A photoionization source is used to detach electrons from molecules with low ionization potentials.

Cette invention concerne un spectromètre de masse à grande vitesse (300) comprenant un ioniseur à décharge incandescente (302); un piège à ions à décharge incandescente (308); un analyseur de masse de temps de vol à décharge incandescente (306); un photo-ioniseur (304); un piège à ions pour photo-ioniseur (310); un analyseur de masse de temps de vol pour photo-ioniseur (306); et un détecteur d'ions (320).
