In this presentation we will show data acquired using a novel hybrid Quadrupole/TWIMS/oa-Tof mass spectrometer, operated with an ESI source. The TWIMS is a stacked-ring ion guide, operated at elevated pressure, with opposite phases of an rf voltage applied to adjacent plates to provide radial ion confinement.  A continual sequence of dc pulses is superimposed on the confining rf to provide ‘waves’ which propel ions through the gas.
