In mass spectrometry, ion transmission is usually achieved by driving an ion funnel with a reversed sine wave radiofrequency. However, the mass range of this conventional ion funnel is limited. In order to overcome this limitation, and to improve the transmission efficiency of the ion funnel, we explore the use of different radiofrequency waveforms for different m/z ranges.

新型射频波形驱动的离子漏斗性能优化。

在质谱法中，离子传输通常是通过以反向正弦波射频驱动离子漏斗来实现的。但是，该常规离子漏斗的质量范围受到限制。为了克服此限制并提高离子漏斗的传输效率，我们探索了针对不同m / z范围使用不同的射频波形。
