Enantiomeric Separation and Quantitation of (±)-Amphetamine,(±)-Methamphetamine,(±)-MDA,(±)-MDMA, and (±)-MDEA in Urine Specimens by GC-EI-MS after …

Abstract

In drug testing, the presence of methamphetamine in urine is generally confirmed by a gas chromatography-mass spectrometry (GC-MS) method. Derivatization of the compound to a perfluoroalkylamide, prior to confirmation, typically yields better chromatographic separation …
