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.
