The mass differences between b ions (or between y ions) are characteristic of the amino acid residues which have been lost, and careful examination of the mass spectrum can yield the peptide sequence from the MS-MS data. For example, Figure 3 shows model data for fragmentation of the MRFA ... WebThe IUPAC Gold Book gives an example: "for the ion C 7 H 7 2+, m/z equals 45.5". Since a mass spectrum x-axis represents a relationship between the ion mass and the number of elementary charges that a given ion carries it contains mass information that may be extracted by a mass spectrometrist. Alternative x-axis notations

WebOne way to do it is to use a mass spectrometer. A variation of this was done in World War II, to separate Uranium isotopes. You can separate them because they have different masses. Uranium-238 has more neutrons than Uranium-235. Therefore, it has more mass. Let's see how my mass spectrometer works. The first step is ionization.
