A system and method are described for producing a modifiable fringing field in a multipole instrument, such as a mass spectrometer or an ion guide. The system includes a conductor arrangement having a first pole pair, a second pole pair and an end device for allowing ions to enter or exit the conductor arrangement. A first power supply provides a first voltage to the first pole pair, such that the application of the first voltage results in a fringing field near the end device. An end device power supply provides an end device voltage to the end device for modifying the fringing field to facilitate the entrance or exit of the ions.

Cette invention se rapporte à un système et à un procédé servant à produire un champs de franges modifiable dans un instrument multipolaire, tel qu'un spectromètre de masse ou un guide d'ions. Ce système comprend un ensemble conducteur comportant une première paire de pôles, une seconde paire de pôles et un dispositif terminal destiné à permettre l'entrée ou la sortie des ions dans l'ensemble conducteur. Une première source d'alimentation applique une première tension à la première paire de pôles, de façon à produire un champ de franges à proximité du dispositif terminal. Une source d'alimentation du dispositif terminal applique une tension au dispositif terminal en vue de modifier le champ de franges, facilitant ainsi l'entrée ou la sortie des ions.
