裂解色谱是分析研究聚合物组成和结构的有力手段。由于它具有灵敏度高、分析速度快及仪器设备简单,适于普及推广。因此,近十年来已越来越得到广泛的采用。激光裂解色谱是七十年代初期发展起来的一种新方法。激光和气相色谱相结合,使得它在对有机化合物、高分子化合物等的分析研究中,具有很大的生命力。本文将介绍:①激光裂解色谱的特点;②三种激光(红宝石、钕玻璃、二氧化碳)裂解装置及相互比较;③激光裂解色谱在对有机及高聚物分析研究中的应用。介绍国内有关单位采用三种激光裂解装置进行分析研究获得的研究成果,借以了解激光裂解色谱的现状。
Pyrolysis chromatography is a powerful tool for analyzing the composition and structure of polymers. Because of its high sensitivity, fast analysis and equipment, simple, suitable for universal promotion. Therefore, the past decade has been more and more widely adopted. Laser pyrolysis chromatography is a new method developed in the early seventies. The combination of laser and gas chromatography makes it great vitality in the analysis of organic compounds, polymer compounds and so on. This article describes: â ’laser pyrolysis chromatography characteristics; â’ ¢ three laser (ruby, neodymium glass, carbon dioxide) cracking device and compared with each other; â ’¢ laser pyrolysis chromatography in organic and polymer analysis of the application. This paper introduces the research results obtained by the domestic relevant units by using three kinds of laser pyrolysis devices to understand the status of laser pyrolysis chromatography.
