  • Trace analyte collection swab
    Patent number: 11506576
    Abstract: A trace analyte collection swab having a collection surface at least partially coated with a microscopically tacky substance to enhance pick-up efficiency is described. In embodiments, the truce analyte collection swab comprises a substrate including a surface having a trace analyte collection area and a coating disposed on the surface of the substrate in the trace analyte collection area. The coating is configured to be microscopically adhesive to collect particles of the trace analyte from a surface when the trace analyte collection area is placed against the surface. In one embodiment, the coating comprises Polyisobutylene.

  • Ammonium salts as IMS positive mode calibrants/reactants
    Patent number: 8461517
    Abstract: An ion mobility spectrometer includes a permeation tube, ammonium sulfate disposed within the permeation tube in solid form, and a heating device configured to heat the permeation tube so as to create ammonia gas to flow within the permeation tube. When an array of sensors of the IMS is placed in contact with an unknown sample, the ammonia operates as a reactant so as to provide detection signals that are provided to a processor unit of the IMS, so as to identify the unknown sample based on its ion mobility spectrum.
