Abstract[English]
In one aspect, an ion 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 provide an electromagnetic field within the passageway for providing radial confinement of the ions and further configured for application of a DC voltage thereto. At least two pairs of auxiliary electrodes are interspersed between the plurality of rods and are configured for application of a DC bias voltage with one polarity to one of said pairs and a DC bias voltage with an opposite polarity to the other one of said pairs to provide a DC potential difference between the auxiliary electrodes and the plurality of rods.[French]
Selon un aspect, est divulgué un filtre 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 fournir 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. Au moins deux paires d'électrodes auxiliaires sont intercalées entre la pluralité de tiges et sont conçues pour l'application d'une tension de polarisation continue ayant une certaine polarité à l'une desdites paires et d'une tension de polarisation continue ayant une polarité opposée à l'autre desdites paires pour fournir une différence de potentiels continue entre les électrodes auxiliaires et la pluralité de tiges.
