title: Detection of synthetic cannabinoids using GC-EI-MS, positive GC-CI-MS, and negative GC-CI-MS.
abstract: Recently, various synthetic cannabinoid (SC) compounds that have been slightly modified at the functional groups have been identified in Japan. However, the structural elucidation of these new compounds using conventional approaches such as gas chromatography-electron impact-mass spectrometry (GC-EI-MS) is difficult. As such, indole and indazole SCs were scanned using GC-MS-EI, positive GC-chemical ionization (CI)-MS, and negative GC-chemical ionization-MS, allowing for efficient structural elucidation of unknown SC compounds. Pure substances have been employed for the study.
