摘要
介绍气相色谱和傅立叶变换红外光谱 (GC FTIR)联用分析技术 ,讨论近年来该联用技术分别在联用系统的 4个主要组成部分———气相色谱、傅立叶变换红外光谱仪、接口系统和计算机控制及数据处理中的作用。叙述该联用技术在联用色谱系统、联用接口技术以及数据处理技术等方面的进展和成就。证明气相色谱法独特的分离能力能够与红外光谱的分子结构鉴别能力完美的结合 ,用于分离鉴定各类复杂混合物 ,其检测灵敏度相当高。另外结合研究实际 ,对联用技术在化学反应产物分析以及反应机理研究中的应用进展进行综述和展望。
The GC/FTIR coupling technique is introduced. The function of coupling technique respectively in four main components of coupling system is discussed. The coupling system includes GC unit, FTIR spectrum, interface system, computer control and data process. Its improvement and achievement in coupling GC system, interface and data processing techniques is described. It proves that the particular separating capacity of GC can combine faultlessly with distinguishing capacity of molecular structure of IR. It is used to separate and identify all kinds of complicated compound, and its detective sensitivity is very high. In addition, based on our work, we review the improvement of application both in analyzing chemical reaction products and in studying reaction mechanism.
