    摘要: 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.

    摘要: An ion processing device includes electrically conductive vacuum manifold segments serially positioned and enclosing a volume along an axis. The segments are electrically isolated from each other and independently addressable by a voltage source. An ion optics device is positioned in the volume. A voltage differential between each manifold segment and the ion optics device is maintained below a maximum value by applying different voltages to respective manifold segments. The voltage differential may be controlled to avoid voltage breakdown in a low-pressure, high-voltage gas environment. The ion optics device may in some cases be an ion mobility drift cell.
