Ionization plasma desorption

3 Plasma Desorption Ionization. Plasma desorption ionization is a highly specialized technique used almost exclusively with a time of flight mass

Plasma desorption ionization (PDI) On applying a plasma beam to a biomolecule, it strips atomic nuclei of their electrons, causing ionization.

A wide variety of soft ionization methods is available, some of which are extensively used such ESI and MALDI, while some others are only applied for specific applications such as FDI and secondary ion mass spectrometry (SIMS). Some of the older techniques can be considered to be outdated and obsolete such as TSI, Cf plasma desorption ionization (PDI), and FAB, because more powerful and/or more user-friendly alternatives have been developed. The various condensed-phase ionization techniques are briefly discussed in this section. The use of metal-ion cationization in chemical and desorption ionization was already reviewed in 1992 [3]. 

Several other desorption ionization methods have been described, including laser desorption ionization and SIMS [21, 34]. In Cf plasma desorption ionization...
