Evaluation of Nonpolar Reversed-Phase Columns Under Supercritical Conditions
July 31st 2008Supercritical fluid chromatography or subcritical fluid chromatography (SFC) is considered a normal-phase technique. In this article, we sought to examine whether it was feasible to use nonpolar columns (for example, C18) under SFC conditions to separate compounds that closely eluted or co-eluted by gradient and isocratic reversed-phase high performance liquid chromatography (HPLC).
