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.
