Abstract: Samples were analyzed by gas chromatography-mass spectrometry (GC/MS), accurate mass measurement, retention index and the abundance of characteristic fragments. An analytical information database of 12 synthetic cannabinoids has been established. The detection limit reached 2.5~30 ng/mL. Unknown samples were analyzed using this method. Two synthetic cannabinoids (JWH-081 and JWH-018) were identified. This method is suitable for the rapid identification of synthetic cannabinoids.
Key words: GC/MS; accurate mass; rapid identification; synthetic cannabinoids
