An ion guide array is disclosed comprising a first ion guide section 1 and a second ion guide section 2 and optionally further ion guide sections. Each ion guide section 1,2 may comprise a plurality of electrodes having an aperture through which ions are transmitted in use. A transfer section is arranged at the exit of the first ion guide section 1 and ions are transmitted radially from the first ion guide section 1 into the second ion guide section 2. The electrodes 1 b,2b in the transfer section may have a radial aperture enabling ions to be transmitted radially from the first ion guide section 1 to the second ion guide section 2. |
