前言采用裂解气相色谱来鉴定高聚物的历史还不很长,最早是将高聚物置于密闭体系(如封管)中抽真空或充惰性气体加热到一定温度使样品裂解,然后将裂解产物导进色谱体系进行分离鉴定,而后是采用简单的热丝裂解装置,直接连到色谱进样系统。60年代裂解色谱发展较慢,因为如此简易的热裂解装置很难使实验条件重复,加上高聚物裂解出来的产物色谱峰 Preface The use of pyrolysis gas chromatography to identify the history of polymers is not yet very long, the first polymer is placed in a closed system (such as sealed tube) or vacuum gas heated to a certain temperature to the sample pyrolysis, and then cleavage products The chromatographic system was introduced for separation and identification, followed by a simple hot-wire lysis unit, which was connected directly to the chromatographic injection system. Cracking chromatography in the 60s slow development, because such a simple pyrolysis device is difficult to repeat the experimental conditions, coupled with polymer cracking of the product peaks
