Other Advanced Mass Spectrometric Techniques

Many other published reports serve as case studies and reveal how MS is used to help determine the provenance of illicit nuclear and radiological materials [94-97, 119-122]. In particular, Becker s 2005 article, Recent developments in isotope analysis by advanced mass spectrometric techniques, gives an in-depth review of methods that have and may be applied to the analysis of samples of interest to the nuclear forensic and counterproliferation conamunities [95]. These arti-... 

Three years earlier, in 2000, Scrivens and Jackson published a review paper with the same title [5], in which revolutionary technical advances in the field were described. In their words, before the so-called revolution, The majority of mass spectrometric studies of polymer systems required optional extraction of the additives from the polymer followed by a chemical or thermal degradation of the polymer itself. Due to partial degradation, the authors make a distinction between direct measurements and indirect measurements [5]. The mass spectra of many synthetic polymers are discussed, but they limit their review to spectra recorded using three ionization techniques, namely field desorption (FD), electrospray ionization (ESI), and matrix-assisted laser desorption/ionization (MALDI). For MS of synthetic polymers prior to the revolution, the authors refer the reader to other sources.
