The effect of mass spectrometry tuning frequency and criteria on ion relative abundances of cathinones and cannabinoids
Forensic Chemistry(2019)
摘要
•Tune check utilizing DFTPP had no effect on relative abundance variation.•Tuning frequency was key variable in reduction of relative abundance variation.•Compounds with extensive fragmentation show more relative abundance variation.•Recommendations are to establish tune-then-run guidelines/maintenance schedules.
