DEVICES AND METHODS FOR GENERATING RESONANCE EXCITATION FOR AN ION MUNIPULATION APPARATUS

Document Type and Number:

WIPO Patent Application WO/2021/155534

Kind Code:

A1

Abstract:

Devices and methods of generating resonance excitation for an ion manipulation apparatus (101) are provided. The ion manipulation apparatus (101) can be operated as an ion filtration apparatus used with particle mass spectrometry system. The devices and methods generate a resonance excitation to effect an ion filtration in a multipole apparatus. The resonance excitation is generated by mixing a radio frequency signal with a plurality of alternative current voltage signals with different frequencies. The resonance excitation can be added to at least one electrode of the multipole apparatus. The generation of mixed alternative current voltage signal is performed in a time domain, therefore no time-consuming inverse Fourier transform is needed, which significantly improves an analysis speed and a throughput of the particle mass spectrometry system.
