Mass spectrometry unveils a world of proteins, from those in cells to fragments found on fossils, as well as the small molecules made by organisms. But this powerful technique oft ...

Mass spectrometry (MS) has emerged as a pivotal tool in the characterization of polymers, providing unparalleled insights into molecular weights, chemical compositions, and sequence distributions.

Mass spectrometry is already a powerful tool for determining what kind and how many molecules are present in a given sample. But most instruments still analyze their molecules one or just a few at a ...

Its true value depends not on the number of detected features but on the reliability of metabolite identification and pathway analysis. Despite well-established guidelines, annotation and definitive ...
