GC/FTIR技术及其进展

The Techniques and the Advances in GC/FTIR

将气相色谱技术的优良分离能力和红外光谱技术独特的结构鉴别能力相结合的联机检测技术———ＧＣ／ＦＴＩＲ，是一种很有使用价值的分离鉴定手段。本文讨论了气相色谱／傅立叶红外光谱联用系统的组成及其功能。阐述了发展中的几种ＧＣ／ＦＴＩＲ新技术：基体隔离技术；冷阱技术；预柱技术以及ＳＦＣ／ＦＴＩＲ技术。同时还论述ＧＣ／ＦＴＩＲ的定量方法。

GC/FTIR,which couples the excellent separation of gas chromatography with the specific identification power of FTIR,is an effective tool for separating and identifying.In this paper,the structure and the function about the system of GC/FTIR are introduced.Some new developing techniques,such as matrix isolation,cold-trap,precolumn and SFC/FTIR are elaborated.At the same time the methods of quantitative analysis in GC/FTIR are discussed.
