MS is a form of chemical analysis used to measure the mass-to-charge ratio (m/z) of atoms and/or molecules in a sample. It is also capable of distinguishing between different isotopes of the same ...

In this article, we take a look at the fundamentals of mass spectrometry, how it works, variations that can be used at each stage of the process and how they can be combined to suit different sample ...

In the early 1940s, the first commercial dispersive spectrometers emerged for UV-Vis applications. This technology is based on the dispersion of light in dependence of its wave-lengths. The dispersion ...

Hundreds of metabolite signals with tandem mass spectra are detected in metabolomic analyses of complex biological matrices 1. Although library matches for some of those spectra may be found in tandem ...

A new test may help to quickly and accurately diagnose the most dangerous and drug-resistant types of bacterial infections. Scientists have found that over the years, bacteria have gradually become ...
