    摘要: In accordance with at least one aspect of this disclosure, a method for identifying a chemical composition includes, collecting a chemical sample and introducing the chemical sample to a detection system, performing, with a differential mobility spectrometer (112), differential mobility spectrometry on the chemical sample to separate ions within the chemical sample into a first constituent group based on a first analysis characteristic. Performing differential mobility spectrometry on the chemical sample further comprises, filtering the ions within the ionized flow such that only ions having a desired mobility pass to a fragmenter, and fragmenting the filtered sample to further dissociate ions within the filtered sample to generate additional ion types having distinctive mobility characteristics.
