简易热丝裂解气相色谱是最先发展的一种裂解色谱方法。其裂解器的主要优点是装置简单、操作简便、温度连续可调等;而其缺点一般认为二次反应较多、裂解的重复性较差。早期国外除了用作定性鉴定外,也用于定量分析上,但报导少而不详。本工作采用改进的简易镍铬热丝裂解色谱法,通过较严格地控制实验条件,主要包括样品用量、样品厚度、操作过程,以及裂解和色谱条件等,对多种高聚物进行了定量分析研究,获得了良好的结果。
Simple pyrolysis gas chromatography is the first development of a pyrolysis chromatography method. The main advantages of its cracker device is simple, easy to operate, the temperature can be continuously adjustable, while its shortcomings are generally believed that more secondary reactions, pyrolysis repeatability is poor. In addition to being used as a qualitative identification of early foreign countries, but also for quantitative analysis, but the report is small and unknown. In this work, an improved simple nickel-chromium hot-wire pyrolysis chromatography method was used to quantitatively analyze a variety of polymers by controlling the experimental conditions strictly, including the sample amount, the sample thickness, the operation process, the cracking and the chromatographic conditions, Research, got good results.
