【摘要】 本文报导用二氧化碳激光作为裂解气相色谱的一种新型裂解源.由于二氧化碳激光的能量能够为透明或半透明的有机化合物所直接吸收,因而克服了红宝石激光或钕玻璃激光在裂解时所遇到的固有困难.一系列定性及定量的裂解谱图数据表明,二氧化碳激光裂解气相色谱对高聚物和其它不挥发性有机物质的研究是一种有用的技术.它在我们实验室有效地鉴别高聚物已逾四年.更多还原

【Abstract】 This paper reports the application of a carbon dioxide laser as a new type of pyro-lytic source in pyrolysis gas ohromatography (PGC).Since the carbon dioxide laserenergy can be absorbed directly by transparent or translucent organic compounds,itovercomes the inherent difficult in pyrolysis which ruby or neodymium glass laser hasmet.A number of qualitative and quantitative data of pyrograms shows that the car-bon dioxide laser PGC is a useful technique for the investigation of polymers and othernon-volatile organic substances.This technique has been used successfully in our labo-ratory to characterize polymers for last few years.更多还原
