摘要
样品前处理是气相色谱分析中耗时最多、最容易引起误差的关键环节,因此样品前处理技术在气相色谱分析中是很重要的环节。本文综述了近年来气相色谱色谱分析各种样品前处理技术新的应用及进展,包括衍生化技术和分离、纯化和富集技术。
Sample is very important in the gas chromatographic analysis due to its time consumed and deviations produced. In this paper, an overview of the progress of sample pretreatment techniques in gas chromatographic analysis, including derivatization reaction technique and pre -concentration technique.
