Methods and apparatus for ion mobility spectrometry and analyte detection and identification
verification system are disclosed. The apparatus is configured to be used in an ion mobility
spectrometer and includes a plurality of reactant reservoirs configured to contain a plurality
of reactants which can be reacted with the sample to form adducts having varying ion
mobilities. A carrier fluid, such as air or nitrogen, is used to carry the sample into the
spectrometer. The plurality of reactants are configured to be selectively added to the carrier …
