Device and method to manipulate ions in multi level system
An apparatus includes multiple levels of ion transport channels, with successive levels coupled by elevator channels. Efficient three dimensional packing provides long path lengths in practical volumes for ion mobility separation with high resolving power. Disclosed elevator configurations provide efficient routing of ion transport channels across levels with low ion loss, enabling ion mobility separation over 100 levels or more. Elevator configurations include (i) opposed traveling waves meeting at an elevator entrance, (ii) external elevator with a wrap-around electrode bank, (iii) external elevator with electrode banks on parallel extension plates, or (iv) elevator operating in surfing mode, in various combinations. Manufacture is aided by printed wiring boards, with interchangeable boards. Assembly with motherboard, spacer block(s), and alignment pins provides efficient distribution of electrode excitations and accurate reproducible positioning.
