    摘要: An ion guide is disclosed comprising a plurality of electrodes. A first device is arranged and adapted to apply a RF voltage to at least some of the electrodes in order to form, in use, a pseudo-potential well which acts to confine ions in a first direction within the ion guide. A second device is arranged and adapted to apply a DC voltage to at least some of the electrodes in order to form, in use, a DC potential well which acts to confine ions in a second direction within the ion guide. A third device is arranged and adapted to cause ions having desired or undesired mass to charge ratios to be mass to charge ratio selectively ejected from the ion guide in the second direction.

    摘要: A mass or mass to charge ratio selective ion trap is disclosed having an increased charge storage capacity. A RF voltage acts to confine ions in a first (y) direction within the ion trap. A DC voltage and/or an RF voltage acts to confine ions in a second (x) direction within the ion trap. A quadratic DC potential well acts to confine ions in a third (z) direction within the ion trap. Ions are excited in the third (z) direction and are caused to be mass or mass to charge ratio selectively ejected in the third (z) direction.

    摘要: A linear ion trap is disclosed wherein an asymmetric voltage waveform is applied to electrodes forming the ion trap which causes ions to become radially separated according to their differential ion mobility. An axial potential barrier is arranged at the exit of the ion trap such that ions having a first differential ion mobility and a first radial displacement are retained axially within the ion trap but ions having a second differential ion mobility and a second radial displacement are ejected axially from the ion trap.
