ABSTRACT:
Desorption/ionization on porous silicon (DIOS) is
a method which extends the application range of matrix-assisted laser desorption/ionization mass spectrometry. This technique eliminates matrix background in the low mass
range, therefore, DIOS is especially advantageous in research on small organic molecules and their metabolites in biological samples. DIOS mass spectrometry was applied for
MDMA (3, 4-methylenedioxymethamphetamine, Ecstasy) impurities identification. Trace components profiling enables to identify by-products characteristic for the synthesis route
of MDMA. Ecstasy, synthetic psychoactive drug is highly popular among young people, and often called as for recreational drug, most commonly used during disco parties. MDMA
enhances feeling of euphoria by increasing the level of neurotransmitters such as serotonin, dopamine and norepinephrine, and causes acute behavioral and psychological
effects. MDMA is almost exclusively produced illegally, primarily in Western Europe. The new method for MDMA impurities profiling has been developed to trace the origin of MDMA
pills. For comparison and classification of the impurity profiles, the principal components analysis was used.
