Abstract: Disclosed herein are embodiments of methods for detecting the presence of and amount of drugs in a sample, particularly a particle sample obtained from a subject. In particular disclosed embodiments, the particle samples are skin particle samples, saliva particle samples, and/or mucous samples isolated from a subject and analyzed using thermal desorption methods combined with a selected detection method.

Abstract: Ion mobility spectrometry (IMS) systems, devices, and associated methods of operation are disclosed herein. In one embodiment, an IMS system includes an ionization region configured to receive and ionize a sample into ionized molecules and a detector configured to detect ionized molecules. The IMS system also includes a drift region in between and directly coupled to both the ionization region and the detector. The drift tube includes a first ion gate proximate the ionization region and a second ion gate proximate the detector. The first and second ion gates are configured to alternately introduce a batch of ionized molecules toward the detector while the other is maintained open, thereby allowing accurate measurement of a drift time of the ionized molecules corresponding to a drift length that is a distance between the first and second ion gates.

Abstract: Various embodiments of ion detection systems, devices, and associated methods of operation are described herein. In one embodiment, a method for ion detection includes separating a target species from other species in an ionized sample of a first polarity, generating ions of a second polarity opposite the first polarity, and contacting ions of the second polarity with the ionized sample to generate emissions after separating the target species from other species in the ionized sample. The method also includes detecting the generated emissions when combining the ionized sampled of the first polarity with the ions of the second polarity.

Abstract: Particular aspects provide novel methods for analysis of ion populations, the methods comprising filtering and selecting an ion population using a low-field dual-gate ion mobility spectrometer comprising a drift tube, the spectrometer operating at a pressure of at least 100 Torr, to provide mobility-selected ions. Certain aspects comprise: (i) subsequently accumulating the low-field selected ions in an ion trap (e.g., an MS ion trap) and mass spectrometry analysis; (ii) introducing the low-field selected ions into a high-field ion mobility spectrometer for separating thereby (optionally followed by mass spectrometry); and (iii) introducing the low-field selected ions into an ion trap mass spectrometer, and subsequently into a second low-field ion mobility spectrometer (e.g., a non-dual gate spectrometer operating at less than about 100 Torr). Additional aspects provide novel apparatus and combination thereof for performing the disclosed methods.
