    Abstract

    A gas chromatograph/mass spectrometer (GC/MS) system equipped with a chiral and an achiral capillary column is used to analyze control methamphetamine, an illicit methamphetamine preparation (“White Cross”), and a simulated illicit methamphetamine synthesis product. Samples are derivatized with N-trifluoroacetyl-l-prolyl chloride (I-TPC) before the GC/MS analysis. The results obtained lead to the conclusion that the resolution on an achiral column is adequate for the determination of methamphetamine enantiomers and impurities, providing the enantiomeric impurity of the l-TPC is known. Four new possible by-products of methamphetamine preparations were identified in the simulated illicit methamphetamine synthesis product.
