裂解色谱与裂解质谱对高分子分析的评价

Evaluation of Py-GC and Py-MS for Analysis of High Polymers

本文报导了在日立 M-80型气相色谱/质谱仪上装上CDS Pyroprobe 100型裂解器,组成既能做裂解色谱/质谱(Py-GC/MS),又能做裂解质谱(Py-MS)的分析裂解系统,通过对一系列的高分子裂解试验,评价了二者的性能。

In this work, first a new analytical pyrolysis system was developed by incorpo-rating pyrolysis--gas chromatography/ mass spectrometry with pyolysis--massspectrometry on Hitachi model M--80 doublc-focusing mass spectrometer. By this sys-tem it became possible to measure characteristic and reproducible GC pyrogram ormass pyrogram for varioug polymers. The performance of Py--GC / MS and Py--MSwasevaluated and compared.
