Enantioselective Determination of Amphetamine-Type Stimulants in Environmental Waters Using SPE and CE-MS/MS. [PDF]
ElectrophoresisABSTRACT The growing concern over drug abuse, particularly involving amphetamine‐type substances (ATS), has led to their monitoring in environmental waters. These chiral compounds, commonly found in river water and wastewater treatment plant (WWTP) effluents, require analytical methods capable of enantiomeric discrimination, as their enantiomers can ...
