tandemmassaspektrometriaa
Tandemmassaspektrometriaa, often abbreviated as MS/MS or 3D MS, is an analytical technique that involves two stages of mass spectrometry. In the first stage, a specific ion of interest, called the precursor ion, is selected from a mixture of ions. This selected ion is then subjected to fragmentation, typically by collision with an inert gas. The resulting fragments, called product ions, are then analyzed in a second stage of mass spectrometry. By measuring the masses of these product ions, information about the structure of the original precursor ion can be deduced.
The power of tandem mass spectrometry lies in its ability to provide highly specific and sensitive analysis.
Applications of tandem mass spectrometry are diverse. In proteomics, it is used to identify and quantify proteins
