Chromatographic study of expert and biological samples containing desomorphine

Expert and biological samples containing desomorphine and concomitant compounds were studied by gas chromatography, chromatography-mass spectrometry, and high-performance liquid chromatography. Some synthetic analogues of desomorphine were identified, and their chromatographic parameters and mass spectra were described. Techniques for the extraction and study of desomorphine and didehydrodesomorphine on a Milichrom A-02 liquid chromatograph were outlined. This information is important for experts in analytical toxicology and criminalistics.
