Abstract: | The objective of this work is the TG and DSC analysis of “Merla” samples as well as the separation and identification of organic compounds by Ultra Fast GC method. The obtained results showed the grouping and the establishment of the degree of the sample’s similarity based in the Euclidean Distance. The cluster was a useful tool to determine if the samples, confiscated from different users by police, were manufactured in the same or different laboratories. Consequently one can conclude if in any city operates one or more drug manufacturing laboratories. |
