高速气相色谱柱上快速升温技术研究进展

摘要

Tradition gas chromatographs, which has disadvantages of long analysis time and not portable, is not fit at field operation. So high speed gas chromatography is widely used in recent year. Separatation characteristic of gas chroma- tography makes accuracy to increase in field analytical system. The development of rapid raise temperature on column in high speed gas chromatography is reviewen in this paper, detail technology is analyzed.%满足现场快速分析有毒有害气体时,常规的高分辨色谱较长的分离时间和仪器的不便携性是不适合的。因此国外将高速或快速气相色谱在现场快速分析检测中的应用已经屡见不鲜,色谱突出的分离特点使分析的准确性大大增加。在高速色谱的实现过程中,快速柱上程序升温是其中的重要方法,本文综述了国内外快速柱上程序升温的技术进展,详细分析了相关的技术概况。
