本文介绍了一种以顶空取样结合气相色谱分析的静态顶空气相色谱技术。重点是介绍在静态顶空气相色谱测定中的各种顶空分析技术,包括常规、全挥发、基于化学反应的相转化、挥发性示踪剂术,以及用于研究化学动力学多次顶空抽提气相色谱技术。本文还例举了一些顶空气相色谱技术的特殊应用。
This paper provides a comprehensive review on the recent development of the static headspace gas chromatography with focuses on various types of approaches including volatile species phase equilibration and non-volatile species derivatization methods used in the headspace analysis. These techniques mainly introduced are the conventional, full-evaporation, phase conversion based on chemical reaction, and volatile-tracer techniques. A multiple headspace extraction technique for study of reaction kinetics is also introduced. Several special applications of headspace gas chromatography with these newly developed headspace analysis technologies are provided.
