Dissolved organic matter (DOM) plays an important role in the global carbon cycle, and an in-
depth analysis of its chemical composition is fundamental to the study of its environmental …

The isotopic exchange approach is in use since the first observation of such reactions in
1933 by Lewis. This approach allows the investigation of the pathways of chemical and …

Glycans, carbohydrates, and glycoconjugates are involved in many crucial biological
processes, such as disease development, immune responses, and cell–cell recognition …

The combined use of hydrogen/deuterium exchange (HDX) and mass spectrometry (MS),
referred to as HDX‐MS, is a powerful tool for exploring molecular edifices and has been …

We report a simple approach for enumeration of non-labile oxygen atoms in individual
molecules of dissolved organic matter (DOM), using acid-catalyzed 16 O/18 O exchange …

Carbohydrates are critical for cellular functions as well as an important class of metabolites.
Characterizing carbohydrate structures is a difficult analytical challenge due to the presence …

Carbohydrates and glycans are integral to many biological processes, including cell-cell
recognition and energy storage. However, carbohydrates are often difficult to analyze due to …

The mass distribution of ions influences separations in ion mobility spectrometry-mass
spectrometry (IMS-MS). Herein, we introduce a method to induce mass distribution shifts for …

A systematic study was performed to investigate the utility of atmospheric pressure chemical
ionization hydrogen–deuterium exchange mass spectrometry (APCI HDX MS) to identify the …

Recent research has revealed that more than 1.3 billion tons of food is wasted globally every
year. The disposal of such huge biomass has become a challenge. In the present paper, we …
