超临界流体色谱（SFC（/span>
1879?*次发现了超临界流体，二十世纪五十年代人们就利用超临界流体进行萃取应用。到二十世纪八十年代越来越多的人把超临界流体作为流动相应用到SFC中。SFC?常见的流动相是二氧化碳，因为趄/span>临界的二氧化碳对很多物质有很好的溶解度和很大的上样量。此外，超临界二氧化碳和其它超临界流体的粗/span>度很低，这使得快速分离和萃取成为可能。超临界流体的易挥发性使得收集的馏分可以在自然条件下的轻杽/span>浓缩、/span>
SFC今天已成为另一种高效液相色谱，亦或正相亦或反相，它是分析热不稳定中小分子的理想工具、/span>任何可溶于甲醇或更弱极性溶剂的分子都可以用SFC分析，很多很难用其它技术分离的强碱可以在SFC上快速高效的分离并有很好的峰形。因为其分离的高速度以及馏分收集的简单易行，SFC技术近来在药物研发咋/span>药物纯化领域的应用也越来越多、/span>SFC要求柱硬件和密封装置在高压下不泄漏。格雷斯公司的轴向SFC柱正是基于这种要求而设计的，此外采用已被广泛接受的轴向加压技术的装填技术可以得到更长的柱使用寿命、/span>
