Scientists from Russia and Germany studied the molecular composition of carbonaceous chondrites – the insoluble organic matter of the Murchison and Allende meteorites This was done in an attempt to ...

BUFFALO, N.Y. ­— Imagine if diagnosis and treatment for devastating conditions such as Alzheimer’s disease could be developed quickly by extensive profiling of protein signatures in human tissues.

Researchers 3D printed a miniature ionizer, a key component of a mass spectrometer. Their device could someday enable an affordable, in-home mass spectrometer for health monitoring. Mass spectrometry, ...

Tandem mass spectrometry is a powerful tool in proteomics. By ionizing peptides and then fragmenting those ions into smaller product ions, researchers can determine the biomolecules’ amino acid ...

When ion-exchange chromatography and mass spectrometry are coupled using electrochemical ion suppression, it allows for the selective and specific analysis of highly polar and ionic compounds. The ...

Researchers 3D printed a mini quadrupole mass filter, a key component of a mass spectrometer, that performs as well as some commercial-grade devices. It can be fabricated in hours for a few dollars ...

Groundwater studies increasingly depend on dissolved-gas tracers to quantify subsurface processes and to support defensible interpretation of aquifer behaviour. Mass spectrometry enables rapid, ...

Various characterisation methods are used to detect and quantify wafer contamination. Fraunhofer IPMS has expanded these ...
