Plasma desorption ionization mass spectrometry (PDMS; also called fission fragment ionization) is a mass spectrometry technique in which ionization of material in a solid sample by bombarding it with ionic or neutral atoms formed as a result of the nuclear fission of a suitable nuclide, typically the Californium isotope 252Cf.
