在这项研究中，一种新型的幽门螺杆菌-气相色谱（Py-GC）系统与现有化学试剂和/或催化剂中的反应性幽门螺杆菌系统结合在一起，并在顺序中开发了一种表征各种功能聚合物的分子结构，因此不适合常规光谱学方法。根据结果，它证明了这个系统是一种强有力的方法，用于各种工程塑料和自然有机化合物的复合和微结构表征。确定共聚物型聚碳酸酯（PC）的末端组和化学成分·根据不同国家的化学成分根据Py-CG确定的Py-CG的化学成分进行的分析·对化学结构中的光降解变化的评估，使用微型胶囊的反应性Py-GC系统，在超临界流体条件下启用了聚合物样品的幽门螺杆菌样本，也开发了其他方法。该系统已成功应用于1）确定纸张样品中的rosin sizing agent和2）多聚碳酸酯中的交叉链接结构的特征。

In this research, a novel pyrolysis-gas chromatography (Py-GC) system combined with reactive pyrolysis in the presence of chemical reagents and/or catalyst was developed in order to characterize the molecular structure of various functional polymers, which were not amenable to conventional spectroscopic methods. As the result, it was proved that this system was a powerful method for the compositional and microstructural characterization of various engineering plastics and natural organic compounds listed below .・determination of end groups and chemical composition of copolymer type polycarbonates (PC)・discriminative analysis of natural resin shellac produced from different countries based on their chemical compositions determined by Py-CG・evaluation of photodegradative changes in chemical structure of silkFurthermore, the reactive Py-GC system using microcapsule, which enabled the pyrolysis of polymer samples under supercritical fluid conditions, was also developed. This system was successfully applied to 1) determination of rosin sizing agents in paper samples and 2) characterization of cross-linking structures in polycabonates.
