In bottom-up proteomics, peptides are separated by liquid chromatography with elution peak
widths in the range of seconds, whereas mass spectra are acquired in about 100 …

Soils, sediments, freshwaters, and marine waters contain natural organic matter (NOM), an
exceedingly complex mixture of organic compounds that collectively exhibit a nearly …

The size and shape of peptide ions in the gas phase are an under-explored dimension for
mass spectrometry-based proteomics. To investigate the nature and utility of the peptide …

The utility of ion mobility spectrometry (IMS) for separation of mixtures and structural
characterization of ions has been demonstrated extensively, including in biological and …

Mass spectrometry (MS) is an established technology in drug metabolite analysis and is now
expanding into endogenous metabolite research. Its utility derives from its wide dynamic …
