Determinação de designer drugs em saliva por paper spray mass spectrometry

Lanaia Itala L. Maciel; Thays C. Carvalho; Igor Pereira; Boniek G. Vaz*


A method has been optimized for quantification of methamphetamine, 3,4-methylenedioxyamphetamine (MDA) and 3,4-methylenedioxy-N-methylamphetamine (MDMA) from saliva samples. Rapid analysis (~ 1 min) of designer drugs in saliva is demonstrated using PSI-MS with a Molecularly Imprinted Polymer (MIP) coated paper as substrate.
