Title (EN) CONCENTRATING MASS SPECTROMETER ION GUIDE, SPECTROMETER AND METHOD
(FR) CONCENTRATION D'UN GUIDE D'IONS DE SPECTROMETRE DE MASSE, SPECTROMETRE ET PROCEDE CORRESPONDANT
Abstract: front page image
(EN)An ion guide includes multiple stages. An electric filed within each stage guides ions along a guide axis. Within each stage, amplitude and frequency, and resolving potential of the electric field may be independently varied. The geometry of the rods maintains a similarly shaped field from stage to stage, allowing efficient guidance of the ions along the axis. In particular, each rod segment of the ith of stage has a cross sectional radius ri, and a central axis located a distance Ri+ri from the guide axis. The ratio ri/RI is substantially constant along the guide axis, thereby preserving the shape of the field.
(FR)Un guide d'ions comprend plusieurs étages. Un champ électrique situé dans chaque étage guide les ions sur un axe du guide. Dans chaque étage, l'amplitude et la fréquence ainsi que le potentiel de résolution du champ électrique peuvent être variés indépendamment. La géométrie des tiges maintient un champ de forme similaire d'un étage à l'autre, ce qui permet de guider efficacement les ions sur l'axe. En outre, chaque segment de tige du Itième étage présente un rayon en section ri, et un axe central situé à une distance Ri+ri de l'axe du guide. Le rapport ri/RI est sensiblement constant le long de l'axe du guide, ce qui maintient la forme du champ.
