Controlled Drug Standards Including Stable Isotope Labeled Standards

Isotopically labeled drugs are an ideal interal standard for drug screening with a mass spectrometer. The isotopically labeled drug exhibits similar chemical behavior to its unlabeled analog through the sample handling process. However, when used with a GC/MS, for example, the m/z difference due to the presence of the isotope will allow for accurate identification and quantification of the suspected drug in the specimen.
