摘要： An ion optical arrangement (1) for use in a mass spectrometer comprises electrodes (11, 12, 14) comprising a multipole arrangement defining an ion optical axis, and a voltage source for providing voltages to the electrodes to produce electric fields. The ion optical arrangement is configured for producing a radio frequency electric focusing field for focusing ions on the ion optical axis. The radio frequency electric focusing field has a varying frequency so as to reduce any mass dependence of ion trajectories through the ion optical arrangement. The ion optical arrangement may further be configured for producing a static electric field in response to a DC bias voltage applied to the multipole arrangement. A superimposed varying electric field may be produced by superimposing an AC voltage upon the DC bias voltage.

摘要： The objective of the presently disclosed subject matter is to provide a mass spectrometer that improves the ionic permeability ratio at the entrance to an ion transport part or the entrance to a mass spectrometry part, and to acquire a high-sensitivity mass spectrum. To reduce the electric-field distortion that is caused by ion loss, electrodes are arranged so that the radius of a circle inscribed within the electrodes of the ion transport part is larger than the radius of a circle inscribed within the electrodes of the mass spectrometry part. The entrance to the electrodes of the mass spectrometry part also can have a tapered, inclined, folded-over, or rounded configuration. Together, these reduce the sharply fluctuating (peak-shaped) distribution of electric potential generated near the entrance to the ion transport part and the entrance to the mass spectrometry part.

摘要： An ion mobility separator 4 and a method of separating ions according to their ion mobility are disclosed. An RF ion guide is provided having a plurality of electrodes that are arranged to form an ion guiding path that extends in a closed loop. RF voltages are supplied to at least some of the electrodes in order to confine ions within said ion guiding path. A DC voltage gradient is maintained along at least a portion of a longitudinal axis of the ion guide, wherein the voltage gradient urges ions to undergo one or more cycles around the ion guide and thus causes the ions to separate according to their ion mobility as the ions pass along the ion guide. The closed loop ion guide enables the resolution of the ion mobility separator to be increased without necessitating a large device, since the drift length through the device can be increased by causing the ions to undergo multiple cycles around the device.
