Performance of Quadrupole Mass Filter with Tapered and Flared Geometry
Anushree Dutta, Pintu Mandal, Nabanita Deb
The performance of a quadrupole mass filter (QMF) is highly sensitive to deviations from ideal electrode geometry. In this work, we investigate the effect of small inward and outwa…
Influence of octupole field on quadrupole mass filter performance in the second stability zone
Anushree Dutta, Pintu Mandal, Nabanita Deb
Radial asymmetry in a quadrupole mass filter (QMF), introduced by symmetric displacement of a diagonally opposite rod pair, modifies the confinement potential and alters the ion st…
Radial asymmetry in quadrupole mass filters: stability, multipole fields and resolution enhancement
Sukanya Jana, Snigdha Bose, Sayel Chakraborty +2
This study examines the effects of radial asymmetry in a linear quadrupole mass filter with circular rods, introduced either by a change in electrode radii or by displacement of a…
Effect of Rod Asymmetry on Field Distortions and Transmission Characteristics in Linear Quadrupole Mass Filters
Sukanya Jana, Santu Nath, Pintu Mandal +1
This article reports the appearance of the octupole and hexadecapole components in the radial potential, which are otherwise absent in a linear quadrupole mass filter of symmetric…
