• Resumen

  • Mass spectrometry of polymers is an exciting area of materials science research: mass spectrometry (MS) can provide information about polymer sequencing, end-groups, and microstructure, as well as serving as a means to determine polymer molecular weight information. This review provides a historical perspective of the development of polymer mass spectrometry, divided into three eras: the small molecule era (1950s and 1960s); the �macromass� era (1970s and 1980s); and the modern era (the late 1980s to the present). The development of pyrolysis combined with electron impact (EI) and chemical ionization (CI) MS are discussed. The history and development of field desorption (FD), secondary ion (SIMS), laser desorption (LD), electrospray ionization (ESI), and matrix-assisted laser desorption (MALDI) mass spectrometry are also presented. The development of mass analyzers is reviewed. Mass spectrometry has become an important technique for characterization of polymers and has been recognized as complementary to conventional techniques such as size exclusion chromatography (SEC) and nuclear magnetic resonance (NMR).
