Abstract
Various embodiments are described herein for an apparatus that can be used to interface a Differential Mobility Analyzer (DMA) with a Mass Spectrometer (MS). The apparatus includes first and second plates with first and second apertures respectively, and an interface region in between the first and second plates. During use, the first aperture receives mobility separated ions from the DMA, the interface region receives a gas flow to prevent gas outflow from the DMA toward the MS, and the first and second plates are configured to receive voltages to generate an electric field there between to guide the mobility separated ions from the first aperture to the second aperture, which then provides the mobility separated ions to the MS.
