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 ...

In chemical research and analysis work, have you ever struggled while looking at electron ionization (EI) mass spectra?“Which ...

Mass spectrometry is an analytical technique that uses an instrument called a mass spectrometer to measure the mass-to-charge ratios of molecular ions. Molecules fragment within the mass spectrometer ...

Ions are accumulated in the Zeno trap before being pulsed rapidly into the TOF, meaning up to 20x more fragment ions can be detected. Enabled by a new level of sensitivity, each MS/MS experiment ...

Plants cannot run from their enemies, so they fight with chemistry. The mustard family, Brassicaceae, is famous for the ...

A novel workflow has quantified more than 50 proteins in individual bacteria and detected stress-associated differences that ...

Just how far mass spectrometry—the use of tools measuring the mass-to-charge ratio (m/z) of one or more molecules present in a sample—has progressed over the past century can be seen in a new exhibit ...
