Greater concentrations may cause system A sensitive, wide-scope, and trace determination of nine residual pharmaceuticals in wastewater using liquid chromatography coupled to quadrupole time-of-flight mass spectrometry (LC-QTOF MS) has been developed and validated. After solid-phase extraction with Cleanert PEP cartridges, sample extracts were ana Quantitative capability of LC-QTOF-MS/MS working in simultaneous full scan MS/MS was also evaluated by five European Proficiency Test samples.

LC-QTOF-MS data were acquired in All-Ions fragmentation mode in both positive and negative electrospray ionization (ESI). LC suspects were identified using two accurate mass LC-QTOF-MS/MS libraries containing pesticides, pharmaceuticals, and other environmental contaminants and a custom exact mass database with predicted transformation products (TPs).
