Normally, the identification of the LSD drug is performed by forensic laboratories, using the Ehrlich spot test. However, this is a nonspecific analysis. Additionally, the Brazilian Federal Police has identified the presence of a new compound in seized blotters: 9,10-dihydro- LSD, an uncontrolled substance. In this work, easy ambient sonic-spray ionization mass spectrometry in the positive ion mode, EASI(+)- MS, was used to characterize LSD and 9,10-dihydro- LSD compositions directly from the surface of blotters. The presence of LSD in the seized blotter samples were also confirmed via high-performance liquid chromatography with ultraviolet detector. In a set of 41 blotters analyzed by EASI(+)- MS, 28 showed positive results for LSD, seven for 9,10-dihydro- LSD, and another six samples showed negative results for both LSD and 9,10-dihydro- LSD. The combination of thin layer chromatography with EASI- MS also demonstrated to be a relatively simple and powerful screening tool for forensic analysis of street drugs. [ABSTRACT FROM AUTHOR] |
