Improving Molecular Formula Assignment of Nitrogen- and Sulfur-Rich DOM in Ultrahigh-Resolution Mass Spectrometry: Validation of Oligopeptides

Abstract Molecular formula (MF) assignment in ultrahigh-resolution mass spectrometry (UHRMS) analyses of dissolved organic matter (DOM) containing multiple non-oxygen heteroatoms (e.g., nitrogen and sulfur) is highly environmentally relevant yet remains challenging. Recent studie...
