Abstract[English]
An ion mass filter for use in a mass spectrometer is disclosed, which includes a plurality of rods arranged in a multipole configuration to provide a passageway through which ions can travel, said plurality of rods being configured for application of RF voltages thereto to generate an electromagnetic field within the passageway for providing radial confinement of the ions and further configured for application of a DC voltage thereto, and at least two pairs of auxiliary electrodes interspersed between the plurality of multipole rods, where one pair forms a first pole of the auxiliary electrodes and the other pair forms a second pole of the auxiliary electrodes. A controller can provide one or more control signals to the DC voltage source so as to switch the polarity of the DC voltage differential between the two poles according to a predefined criterion.[French]
Est divulgué un filtre de masse ionique destiné à être utilisé dans un spectromètre de masse, qui comprend une pluralité de tiges agencées dans une configuration multipolaire pour former un passage à travers lequel peuvent se déplacer des ions, ladite pluralité de tiges étant conçues pour l'application de tensions RF à celles-ci afin de générer un champ électromagnétique au sein du passage pour assurer un confinement radial des ions et en outre conçues pour l'application d'une tension continue à celles-ci, et au moins deux paires d'électrodes auxiliaires intercalées entre la pluralité de tiges multipolaires, une paire formant un premier pôle des électrodes auxiliaires et l'autre paire formant un second pôle des électrodes auxiliaires. Un dispositif de commande peut fournir un ou plusieurs signaux de commande à la source de tension continue de sorte à commuter la polarité du différentiel de tensions continues entre les deux pôles en fonction d'un critère prédéfini.
