Abstract
An interface for an ion mobility spectrometry-mass spectrometry (IMS-MS) system includes a first ion guide for receiving ions from an IMS drift cell, and a second ion guide for receiving ions from the first ion guide, and positioned in a chamber separate from the first ion guide. Electrodes of the second ion guide subject the ions to an axial DC electric field while the second ion guide is held at a lower pressure than the first ion guide. In some embodiments, the first ion guide may be an ion funnel and the second ion guide may be a linear multipole device.
