Detection of amphetamine and methamphetamine-type materials in pharmaceutical and biological fluids by fluorometric labeling.

A rapid and sensitive method for detecting amphetamine and methamphetamine in drug preparations and biological fluids has been developed. Amphetamine and methamphetamine in pharmaceutical and clandestine drug preparations can be easily screened from other contaminating drugs and readily identified by their fluorescence, with subsequent separation accomplished by TLC. The same general procedure can also be used to detect amphetamine and methamphetamine in human urine at concentrations of 0.1 mug/ml.
