INTRODUCTION OF IONS INTO ION CYCLOTRON RESONANCE CELLS

摘要

The invention relates to a method and a device for introducing ions into an ICR cell of Fourier transform ion cyclotron resonance mass spectrometers, in particular with a reduced the magnetron orbit. The invention is based on applying at least one gated DC voltage to a mantle electrode of the ICR cell prior to the excitation of the cyclotron motion such that injected ions are deflected inside the ICR cell in at least one radial direction.
