Mass spectrometric techniques play an important role when investigating nuclear material for nuclear forensic purposes. The elemental and isotopic composition of materials are of particular interest. The versatility and the sensitivity of mass spectrometric methods provide access to a wealth of information inherent to the nuclear material. To this end, different variants of mass spectrometry are applied. They provide hints on the history and on the intended use of the material, based on elemental and isotopic data. This includes major constituents of the material, as well as trace impurities and it is applicable to bulk samples as well as to individual micrometer sized particles. The choice of the analytical method to be applied depends on the physical and chemical appearance of the material and on the information to be obtained. Recent progress in the development and application of the most prominent mass spectrometric techniques (thermal ionization mass spectrometry, inductively coupled plasma mass spectrometry and secondary ion mass spectrometry) are provided in the presetation.
