说明
分析说明
The fluoroamphetamines (FA) are a group of "designer" stimulant drugs in the amphetamine family. Four members of the FA family are shown here isolated from urine using Supel-Select SCX SPE and separated in under 3 minutes on an Ascentis Express HILIC column. Cerilliant CRMs were used to ensure reliable MS identification and quantification.
