- 論文の詳細を見る
A Curie-point direct injection probe to be coupled to a mass spectrometer was developed. Its flash heating, wide range temperatures (160~1,040°C), reproducible temperature (±1°C) and direct connection to the ion source of a mass spectrometer were effectively applied to the polymer analysis. Pyrolysis-mass spectrometry by use of this device enabled the discrimination between a copolymer and the corresponding blended polymer of {poly(styrene) and poly(fluorostyrene)}, because of the decreased secondary reactions among the pyrolyzates, when compared with pyrolysis gas chromatography (Py-GC). As compared with Py-GC, the new technique can elute larger pyrolyzates, only within a few minutes, which provide compositional and structural information of the polymer samples. The rapid analysis of an additive in a polymer is also reported in this paper.
