Fast atom bombardment ionization (FAB)
Ionization of molecules initiated by a beam of neutral atoms with translational energies in the keV range. Labile molecules susceptible to dissociation are dissolved in an involatile liquid matrix that absorbs the energy of the bombarding atoms to form a selvedge region above the liquid surface in which ionization of the molecules occurs.
Note: Positive ions (e.g., protonated or cationized molecules) or negative ions (e.g., deprotonated molecules) are formed depending on the polarity of ionization.
