Abstract

The article presents the methodology of forensic chemical research of
trace amounts of unknown substances using gas chromatography-mass
spectrometric analysis.
Established: retention time, molecular and fragmentation ions, their intensity,
individual fragmentation of a substance, name, chemical structure and structural
freemule.
These parameters are recommended for the detection of controlled substances in
complex matrices.
This method has proven to be very sensitive, fast and easy to use
