Scope

Main technical content: This document specifies the online solid-phase extraction (AOE) system-ultra-high performance liquid chromatography-tandem mass spectrometry testing method for 13 drugs and their metabolites, including morphine, codeine, O6-monoacetylmorphine, methamphetamine, 3,4-methylenedioxymethamphetamine (MDMA), amphetamine, benzoylecgonine, ketamine, norcocaine (NK), methcathinone (MC), cocaine, 3,4-methylenedioxyphenylacetic acid, and the population marker cotinine in urban wastewater. The wastewater samples are subjected to pH adjustment, centrifugation, and filtration, then enriched, purified, and concentrated by the online solid-phase extraction system, and detected by the multiple reaction monitoring (MRM) mode of liquid chromatography-tandem mass spectrometry. The analysis is conducted based on retention time, mass spectrometry characteristic fragment ion peaks, and the relative abundance ratio of ion pairs, with quantification performed using internal standards.
