Abstract
One aspect of the present invention is to extract multiple ionic species in a FAIMS into one or more IMS drift tubes simultaneously. By adjusting FAIMS operational parameters, ions in FAIMS are detected on IMS detectors through separation in FAIMS and/or separation and collection in the IMS. This method provides a continuous separation of specific ions from an ion swarm by employing a high-field differential mobility analyzer (FAIMS) with a plurality of orthogonal transitions paths spaced incrementally along the electrodes which allow additional separation by a conventional IMS drift tube. The components of the sample can be collected or detected.
