Zupercritique excels at separating and purifying chiral compounds and natural products because it’s faster, uses much less solvent, and overall is a less expensive and greener method that exceeds high pressure liquid chromatography HPLC in performance for chiral separations.
Supercritical Fluid Chromatography
The interest of supercritical-fluid chromatography SFC is that high temperatures are not needed to elute heavy ends and that the mechanism for extending the upper limit of simdist depends only on sample solubility into the supercritical mobile phase. Thus, SFC could be the tool of choice for better determination of conversion in heavy petroleum-fraction processing.
