Abstract:
The purpose of this work is to study the possibility of using cartridges with a mixed sorbent C8/SAX for the extraction of synthetic cannabimimetic metabolites MDMB (N)-073F from urine. It was used enzymatic hydrolysis of urine, solid phase extraction using cartridges C8/SAX and C8/SCX with mixed phase, derivatization and gas chromatography with a mass spectrometric detector. The results of the study allow us to recommend cartridges for solid-phase extraction with an anion-exchange phase (C8/SAX or SAX) when conducting a targeted study for the presence of cannabimimetics metabolites that have compounds with a carboxyl group as the main metabolites.
