Abstract:
In accordance with various aspects of the present teachings, methods and systems for differential mobility spectrometry are provided herein for simultaneously applying a plurality of SV/CV combinations to subsets of a population of ions generated by one or more ion sources. In various aspects, DMS devices in accordance with the present teachings can provide multiple channels (e.g., 2, 3, 4, 5, 6, or more) for operating in parallel and within which different electrical fields can be generated for filtering sample ions within those channels based on the characteristic mobilities of the ions within each channel. In this manner, devices and methods in accordance with the present teachings can, in various aspects, enable improved duty cycle, increased throughput, decreased sample consumption, increased sensitivity for a plurality of ions of interest, and/or increased resolution.

Claim (Index 1):
A differential mobility spectrometer, comprising:\n a plurality of electrodes extending from an inlet end for receiving sample ions contained within a drift gas to an outlet end for transmitting at least a portion of said sample ions, wherein said plurality of electrodes comprise:\n a first pair of opposed filter electrodes extending from the inlet end to the outlet end and configured to receive a first portion of the sample ions therebetween, wherein the first pair of opposed filter electrodes is configured to be electrically coupled to a power supply so as to generate a first differential mobility electric field between the first pair of opposed filter electrodes; and \n a second pair of opposed filter electrodes extending from the inlet end to the outlet end and configured to a second portion of the sample ions therebetween, wherein the second pair of opposed filter electrodes is configured to be electrically coupled to the power supply so as to generate a second differential mobility electric field between the second pair of opposed filter electrodes, \n wherein the first differential mobility electric field and the second differential mobility electric field are configured such that the first pair of electrodes and the second pair of electrodes transmit to the outlet end selected portions of the sample ions having different mobility characteristics, and wherein the first and second pair of opposed filter electrodes define first and second channels extending along the length of the plurality of electrodes, wherein the first differential mobility electric field is generated in the first channel and the second differential mobility electric field is generated in the second channel, and each filter electrode comprises a planar conductive surface partially defining at least one of the channels, wherein the planar conductive surfaces of the electrodes in each pair are parallel to one another.
