    Abstract

    Mass spectra of several commonly abused drugs and their deuterated analogs are compared and evaluated with emphasis on the selection of suitable ions for selective ion monitoring when the isotopic analogs are used as the internal standards in a quantitative determination process. Ions selected for this purpose should be of relative high mass with significant intensities, retain at least three labeling isotopes, and be free of interference from the corresponding compound.
