Tandem mass spectroscopy

Tandem mass spectrometry (MS-MS) currently is an important technique, both in fundamental studies concerning the behaviour and structure of gas-phase ions, and in many analytical applications of MS. The history of MS-MS can be considered to go back to the observation and explanation of metastable ions by Hipple and Condon in 1945 The following scheme explains how Tandem MS works. Once samples are ionized (by ESI, MALDI, EI, etc.) to generate a mixture of ions, precursor ions of a specific mass-to-charge ratio (m/z) are selected (MS1) and then fragmented (MS2) to generate a product ions for detection.The selection-fragmentation-detection sequence can be further extended to the first-generation product ions Tandem mass spectrometry is the leading technique in sequence determination of peptides and other biomolecules. 57,59,61-65 The technique involves mass selection of the target peptide ion, fragmentation of the mass-selected ion, and m/z analysis of the fragment ions
