A SIMPLE AND RAPID METHOD FOR THE IDENTIFICATION OF AMPHETAMINE AND METHAMPHETAMINE HYDROCHLORIDES BY MASS-SPECTROMETRY

In order to determine amphetamine and metamphetamine, we have used a m ethod never used before in the legal practice. The aim of our work was to optimize the measurement conditions for the rapid and accurate det ermination of amphetamine and metamphetamine. We have developed a meth od which makes possible the unambiguous identification of the hydrochl orides of the hallucinogens amphetamine and metamphetamine, even when these two are present simultaneously. In our work we have used the amm onium salt technique. The information available from the mass spectra (molecular ion, appearance of characteristic fragments) are dependent on the temperature of the direct sample and the ionisation energy. As a consequence, we have primarily studied the influence of the above tw o parameters upon the mass spectra.
