Non-target screening using chromatography coupled to high-resolution mass spectrometry is a powerful tool in environmental ...

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.

Nitrotyrosine, a nitrated derivative of the amino acid tyrosine, serves as an established biomarker for nitrosative stress and related pathophysiological conditions. Its formation occurs through the ...

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 ...

For biologists, seeing is believing. But sometimes biologists have a hard time seeing. One particularly vexing challenge is seeing all the molecules in an intact tissue sample, down to the level of ...

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 ...

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