Simulation Study of a Novel Cylindrical Direct Current‐Ion Funnel to Improve Ion Transmission
The new cylindrical DC-ion funnel developed in this study has improved sensitivity solely through a DC electric field, achieving technological innovation without RF. Moreover, the novel structure proposed in this paper has a simpler structure and higher ion transmission efficiency than the reported spherical DC-ion funnel, making it highly suitable as the drift tube of PTR-MS. In addition, the novel cylindrical DC-ion funnel is highly expandable and is expected to be used in other mass spectrometry techniques for sensitivity enhancement.
