超临界流体色谱出现于1962年,并得到了发展。到八十年代初这种色谱过程的研究和应用,更加引起各国色谱工作者的重视。 超临界流体色谱是指在色谱过程中,流动相不是一般的气体或液体,而是一种经过高度压缩的气体。这是在操作温度高于流动相的临界温度,和操作压力高于流动相的临界压力下,进行色谱过程的。CO_2在超临界
Supercritical fluid chromatography appeared in 1962 and has been developed. By the early 1980s, the research and application of such chromatographic processes have drawn more attention from chromatographers in various countries. Supercritical fluid chromatography refers to the chromatographic process, the mobile phase is not a general gas or liquid, but a highly compressed gas. This is done at operating temperatures above the critical temperature of the mobile phase and at operating pressures above the critical pressure of the mobile phase. CO_2 in the supercritical
