Article Abstract PDF Behind the Science Talking with analytical scientists who are trying to solve today’s toughest problems. As supercriitque high pressure liquid, or supercritical fluid, using CO 2 is a smart solvent for its low viscosity and high diffusivity needed in today’s demanding purification labs and also a sustainable solvent as it is reused after being discarded from other industrial processes.

SFC 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 chromatographhie HPLC in performance for chiral separations.

Innovation through collaboration at our Experience Design Center. The principles of SFC are similar to those of liquid chromatography, however SFC typically uses carbon dioxide as the main mobile phase. Ask the Column Coach: The mobile phases used in SFC are gases such as freon, ethylene, or carbon dioxide.
