Wastewater surveillance in 2022 used 24-hour composite samples from 15 WWTPs spanning ~100,000 to >1 million population ...

The sample throughput of high-sensitivity liquid chromatography-mass spectrometry (LC-MS) based proteomics analysis is restricted by the pressure limitations of LC and column hardware, with some ...

Tandem mass spectrometry is a powerful tool in proteomics. By ionizing peptides and then fragmenting those ions into smaller product ions, researchers can determine the biomolecules’ amino acid ...

Music festivals concentrate higher-risk, polydrug-use behaviors than general populations, enabling efficient surveillance of emerging substances, co-ingestion patterns, and context-dependent ...

Mass spectrometry (MS) is an analytical technique used to identify and quantify molecules based on their mass-to-charge ratio (m/z). It provides valuable information about the chemical composition, ...
