    Data for Quaternary ammonium compounds (QACs) in wastewater influent and effluent collected throughout the COVID-19 pandemic
    (2024-01-08) Mahony, Anna K; McNamara, Patrick J; Arnold, William A; mahon445@umn.edu; Mahony, Anna K; University of Minnesota Environmental Engineering Arnold Lab
    The dataset contains the concentrations of quaternary ammonium compounds detected in influent and effluent wastewater, as well as absolute recoveries of QACs spiked into influents and effluents, and absolute recoveries of isotopically labeled surrogate standards, spiked into all samples. After extraction from wastewater, samples are analyzed on a liquid chromatography tandem mass spectrometry (LC-MS/MS), specifically a triple quadrupole mass spec. Raw data from this instrument is provided as well, in the "Raw QQQ data" tab.
