Abstract

This study proposes a planar geometry mass analyzer which has fields and performance like that of a reference Orbitrap. The planar geometry taken up for investigation consists of two planar surfaces with concentric ring electrodes on each facing surface. Appropriate potentials are applied to the individual rings for effecting trapping of ions. The study used both single particle and multi-particle simulations. In the multi-particle simulations spatial and energetic distribution as well as space charge effects in the ion ensemble have been incorporated. The performance of this planar geometry has been compared to that of a reference Orbitrap by computing (1) the variation in potential along the principle directions, (2) ion trajectories and (3) induced image currents.in the two geometries. The potentials applied to the ring electrodes were optimized to improve the electric field inside the planar geometry. (C) 2017 Elsevier B.V. All rights reserved.
