A recently filed patent (Publication Number: US20240038476A1) describes an ion guide with a unique design aimed at efficiently containing ions. The ion guide consists of two surfaces facing each other with a gap in between, housing a series of electrodes. These electrodes are strategically arranged in two sets on each surface, with specific shapes and configurations. The first set of electrodes on one surface interacts with the second set on the opposite surface to create an ion containment space within the gap. By applying different RF voltages to the electrodes, the ion guide generates electric fields that prevent ion movement towards the surfaces, ensuring effective containment.

Furthermore, the patent details variations in electrode shapes, such as L-shaped, T-shaped, or Y-shaped, to optimize ion containment. The arrangement of electrodes allows for the generation of surface containment electric fields and edge containment electric fields that work together to inhibit ion movement in different directions within the ion containment space. The use of phase-shifted RF voltages on opposing edge portions of the electrodes enhances the effectiveness of the containment system. Additionally, the patent explores the use of printed circuit boards (PCBs) as surfaces for the ion guide, showcasing a practical application of the technology in various settings. Overall, the innovative design of the ion guide presented in the patent aims to improve ion containment efficiency and has the potential for diverse applications in ion manipulation and analysis.
