Abstract
Une méthode et un dispositif qui combinent un guide d'ions linéaire à deux dimensions ou un périphérique de stockage d'ions à deux dimensions en tandem avec un analyseur de masse à temps de vol pour analyser des espèces chimiques ioniques générées par une source d'ions. La méthode améliore le cycle de travail et par conséquent, la sensibilité globale de l'instrument en ce qui concerne les espèces chimiques analysées.
