摘要
介绍了中国科学院生态环境研究中心研制的ＰＩＤ－１００Ｄ型双气路、双进样口、双色谱柱、单检测器的便携式光离子化气相色谱仪。该仪器具有重量轻、线性范围宽、灵敏度高的优点，苯的检出限低至０２３ｐｇ，优于配备氢火焰检测器两个数量级。
A photoionization gas chromatograph is described in this article. This portable chromatograph is composed of two injectors, two columns and single PID. It is light in weight and has many other advantages, such as wide linear dynamic range and higher sensitivity. The detection limit is as low as 0.23 pg for benzene, two orders of magnitude better than the chromatograph with FID.
