摘要
热裂解气相色谱-质谱联用(pyrolysis gas chromatography-mass spectrometry,Py-GC-MS)技术是将热裂解技术与气相色谱-质谱联用技术相结合。Py-GC-MS不仅适用于常规聚合物的定性检测,还适用于分析难溶以及复杂的有机物质,尤其适用于分析复杂高分子物质。通过改变Py-GC-MS的裂解条件以及结合红外光谱等技术可以对复杂样品进行准确的定性分析。本文介绍了Py-GC-MS的发展过程、基本原理、特点、裂解装置的类型及其应用范围,并介绍了该技术在微量物质、食品包装材料和未知物分析中的应用。
Pyrolysis gas chromatography-mass spectrometry （Py-GC-MS） technology is a kind of pyrolysis technology combined with gas chromatography-mass spectrometry. Py-GC-MS is not only suitable for the qualitative detection of conventional polymers, but also suitable for the analysis of refractory and complex of organic matters, especially for the analysis of complex polymer materials. This technology can be used for accurate qualitative analysis of complex samples by changing the pyrolysis conditions of Py-GC-MS and combining with infrared spectroscopy technology and etc. This paper introduced the development process, basic principles, characteristics, pyrolysis unit types and application scopes of Py-GC-MS and its applications in the analysis of trace substances, food packaging materials and unknown materials.
