文摘

A Gtip SPE and UPLC–MS/MS was established for determining synthetic adulterants. Fenfluramine, phenolphthalein, bumetanide, and sibutramine were analyzed. Graphene was used as sorbent for a microscale SPE using pipette tip as cartridge. It is good at testing low level contaminates resulted from violation of regulation.
