The invention relates to instruments for storing ions in more than one ion storage device and to the use of the ion storage bank thus created. The invention consists in designing several storage cells as RF multipole rod systems, filling them with damping gas and arranging them in parallel. Each pair of pole rods is then used jointly by two storage cells so that the ions collected can be transported from one storage cell to the next by briefly applying DC or AC voltages to individual pairs of pole rods. The ions can thus be transported to storage cells in which they are fragmented or reactively modified, or from which they can be fed to other spectrometers. In particular, a circular arrangement of the storage cells on a virtual cylindrical surface makes it possible to accumulatively fill the storage cells with ions of specific fractions from temporally sequenced separation runs. |
