Abstract: Apparatus and methods are disclosed to improve performance of ion mobility separation. Deleterious bend effects are counteracted by adjusting phase shifts between adjoining traveling wave sections at bends; superior trajectories and performance are achieved. Improvements are also achieved by arranging serpentine paths primarily along a lengthwise direction of a substrate, thereby reducing the number of bends. An ion mobility spectrometers is coupled to a mass spectrometer, and intermittent traveling waves improve sample utilization or reduce total time required for combined ion analysis with both modalities.

Abstract: A mass spectrometer that includes a mass filter and a TOF mass analyzer receives the ion beam from an ion source device that ionizes a compound of a sample. The mass filter selects a precursor ion mass range and the mass analyzer mass analyzes the mass range. A continuous flow of selected precursor ions is maintained between the mass filter and the mass analyzer. A first set of parameters is applied to the mass spectrometer to produce a resolution above a first resolution threshold. A space charge effect is detected by determining if the measured TIC exceeds a TIC threshold or the measured resolution is less than the first resolution threshold. If a space charge effect is detected, at least one precursor ion transmission window with a width smaller than the mass range is applied to the ion beam by the mass filter and mass analyzed to reduce the space charge.
