Application of polypropylene tubes as single-use and low-cost sorptive extraction materials for the determination of benzodiazepines and zolpidem in water samples
Abstract(#br)This work presents a method for the simultaneous determination in water of 17 benzodiazepines (BZPs) and a related pharmaceutical (zolpidem) by extraction with low-cost polymeric sorbents followed by liquid chromatography-tandem mass spectrometry (LC–MS/MS). Different polymers were considered: polydimethylsiloxane (PDMS), polypropylene (PP), and polyethersulfone (PES), providing the second one (PP) higher responses.
