摘要
回顾光离子化技术的发展历程,介绍了光离子化技术的优缺点、光离子化检测器的基本工作原理和结构,着重分析了电离室内部的电离微观机制。并以国产仪器GC-4400型便携式光离子化气相色谱仪为主,介绍了国内外近期PID技术的若干最新发展。
The development course of photoionization technique is reviewed. The merit and disadvantage of PID technique,the basic working principle and structure of PID is introduced. And the inner ionization microcosmic mechanism of chamber is especially analyzed. The homemade GC -4400 portable photoionization gas chromatogram is taken as backbone. And some latest development of PID technique of home and abroad is introduced.
