Evolved gas analyses by pyrolysis were carried out for 10 kinds of polymers using a newly developed prototype of Skimmer interface-connected [TG/DTA]/[Ion Attachment Ionization-TOFMS]. This prototype has an advantage of the real-time monitoring of pyrolyzed species because of no transformation of the evolved species with the skimmer interface and no fragmentation during ionization by the Ion Attachment Ionization technique. On the other hand, the combination of TG/DTA results and mass spectra offers the discrimination of polymers with the same chemical structure and different thermal properties. Examples were presented in this study.
