High-performance liquid chromatography/high-resolution mass spectrometry (LC/HRMS) can be used to perform non-targeted analysis of dissolved organic matter (DOM) in environmental water at the molecular level without specifying target analytes prior to measurement. Pretreatment of samples subjected t...
