Abstract
A method for detecting a chemical substance includes collecting a sample of a substance of interest and mixing the sample and at least one additive within a reaction chamber. The at least one additive includes a plurality of isotopes. The method also includes producing a plurality of adduct ions of the sample. The plurality of adduct ions has a plurality of isotopes. The method further includes performing a spectrometric analysis of the plurality of adduct ions and performing sample identification using comparative spectrometric data of the isotopes of the plurality of adduct ions.
