Method for operating a quadrupole device with voltage waveforms
The patent US12040173B2 outlines a method and apparatus for operating a quadrupole device, specifically focusing on the manipulation of ion intensity in synchronization with a repeating voltage waveform. The method involves applying a main drive voltage along with at least one auxiliary drive voltage to the quadrupole device while controlling the flow of ions. The intensity of these ions is varied in a manner that aligns with the periodic nature of the voltage waveform, allowing for enhanced control over ion transmission and selection based on their mass-to-charge ratio. The claims detail various approaches to achieve this, including trapping ions upstream, selectively releasing ions, and generating ion packets.
Additionally, the apparatus described in the patent includes the necessary components to implement the method, such as voltage sources and devices that modulate ion intensity. The design allows for the periodic variation of ion intensity, ensuring that a greater number of ions experience specific phases of the voltage waveform, which can lead to improved transmission efficiency. The claims also specify configurations for the quadrupole device, emphasizing its role as a quadrupole mass filter capable of filtering ions based on their mass-to-charge ratio. Overall, the patent presents a comprehensive framework for optimizing ion manipulation in quadrupole devices, which could have significant implications for analytical and mass spectrometry applications.
