Application of GC-MS method and modern IT-system for analysis of multicomponent mixtures system of "designer’s" cannabinoids in conditions of chemical examination
The extraction with ethyl acetate at the temperature of 20-22 оC in a strongly alkaline medium is proposed for the isolation of the group of synthetic cannabinoid drugs. The specialties of separation of the multicomponent mixtures of cannabinoids with the different structure and their identification by GC-MS method are studied by example of the expert sample of “designer’s” drug. The chromatography parameters of the individual cannabinoids are determined and the presence of dependency of retention degree of analytes in the stationary phase on their chemical structure is founded. The possibility of optimizing the process of identification of cannabinoid by GC-MS method which is based on the use of automated IT-system in complete set with the “AIPSIN MS Database” mass-spectral libraries and “Identifier” module is shown.
