The ability to measure mass to charge ratio of the ions in mass spectrum is the most important feature of the high-resolution mass spectrometers. An analyte's identification can be progressed further ...

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 ...

Mass spectrometry is a powerful analytical method used to identify and characterize molecules. People often mistakenly think that the data outputted by the technique come in the form of a mass ...

During the process of research and development of antibody drug molecules, an essential step is determining the sequence of the antibody. Mass spectrometry technologies have advanced so far as to make ...

The gaseous sample comprising of the VOCs to be examined (for instance, ambient air) is directly sampled into the PTR mass spectrometer without preparing any samples. The PTR ionization source is the ...

Scientists have simulated, for the first time, the merger of two black holes of vastly different sizes, with one mass 100 times larger than the other. This extreme mass ratio of 100:1 breaks a barrier ...
