Common matricies include glycerol and 3-nitrobenzyl alcohol (3-NBA). This technique is very closely related to (if not part of) secondary ion mass spectrometry. FAB is a relatively soft ionization technique and produces primarily protonated molecules denoted as and deprotonated molecules such as . The nature of its ionization products places it close to electrospray and MALDI.
