Method for operating a quadrupole device with voltage application
The patent US12074019B2 outlines a method and apparatus for operating a quadrupole device, which is integral to mass and ion mobility spectrometry. The method involves applying multiple voltages, including a main AC quadrupolar voltage, an auxiliary AC quadrupolar voltage, an AC dipolar voltage, and one or more DC voltages. These voltages are strategically selected to enable the quadrupole device to function within two or more stability regions simultaneously. The AC dipolar voltage is specifically designed to attenuate ions associated with at least one of these stability regions, enhancing the device's ability to manage ion trajectories effectively.
The apparatus described in the patent includes a quadrupole device with four electrodes and one or more voltage sources that facilitate the application of the aforementioned voltages. The configuration allows for the attenuation of ions corresponding to multiple stability regions, rather than just a single selected region, which can include X-band or Y-band stability regions. Additionally, the design may incorporate digital voltage sources, and the dipolar voltage can increase the radial amplitudes of certain ions as they traverse the quadrupole device. This innovative approach aims to improve the performance and versatility of mass and ion mobility spectrometers, potentially leading to more precise analytical capabilities in various scientific applications.
