    • Method for improving the performance of a preparative batchwise Super Critical Fluid Chromatographic separation for the recovery of a target fatty acid or derivative thereof, or of a group of target fatty acids or of derivatives thereof from a mixture, characterized in that the said Super Critical Fluid Chromatographic separation employs a chromatographic column charged with a stationary phase chosen from the group consisting of aluminium oxide or aluminium oxides, titanium oxide or titanium oxides, silica gel or silica gels, amino propyl modified silica gels, diol modified silica gels, phenyl modified silica gels and “reversed phase” phases, the former in turn chosen from the group consisting of RP 18, RP8 and RP3, and in that the said Super Critical Fluid Chromatographic Separation further employs a mobile phase chosen from the group consisting of ethylene, propane, ammonia, dinitrogen dioxide and CO2, wherein in the said method, during the run of the said mixture on the chromatographic column, a pressure and/or temperature gradient is applied to the chromatographic column during the elution of the target fatty acid or derivative thereof.
    • 用于改进用于从混合物中回收目标脂肪酸或其衍生物或一组目标脂肪酸或其衍生物的制备型间歇超临界流体色谱分离的性能的方法,其特征在于所述超临界流体 色谱分离采用带有选自氧化铝或氧化铝,氧化钛或氧化钛,硅胶或硅胶,氨基丙基改性硅胶,二醇改性硅胶,苯基改性硅胶的固定相的色谱柱 和“反相”相,前者又选自RP 18,RP 8和RP 3组成,并且所述超临界流体色谱分离还采用选自乙烯,丙烷,氨的流动相 ,二氧化氮和二氧化碳,其中在所述方法中,在所述混合物在色谱上运行期间 图示柱中,在目标脂肪酸或其衍生物洗脱期间,将色谱柱施加压力和/或温度梯度。
