A reengineered mass spectrometer prototype can now analyze up to a billion molecules simultaneously, a leap from conventional instruments that handle only a few at a time. The advance, reported in ...

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 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 ...

A new mass spectrometry technique sorts molecules to capture those of lower abundance. For scientists, a molecule’s weight can help determine its makeup. For measures like this, researchers turn to a ...

Mass spectrometry (MS) is an analytical technique used to identify and quantify molecules based on their mass-to-charge ratio (m/z). It provides valuable information about the chemical composition, ...

At the University of Oxford, Justin Benesch studies assemblies made between proteins called molecular chaperones and the proteins they protect in cells. These assemblies slow the formation of amyloid ...
