To identify specific chemicals or molecules in the life sciences and medical research, scientists often use mass spectrometry (MS), usually paired with liquid chromatography (LC). These technologies ...

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 ...

Mass spectrometry measures the mass-to-charge ratio of ions by ionizing chemical compounds to produce charged molecules. A typical mass spectrometer consists of three parts: a detector, a mass ...

The prototype ion trap contains hundreds of inlets and outlets, mimicking how biology moves things into and out of cell nuclei. Credit: Lori Chertoff/The Rockefeller University When J. J. Thomson ...
