Supercritical fluid chromatography (SFC) is a form of normal phase chromatography that uses a supercritical fluid such as carbon dioxide as the mobile phase. It is used for the analysis and purification of low to moderate molecular weight, thermally labile molecules and can also be used for the separation of chiral compounds. Principles are similar to those of high performance liquid chromatography (HPLC), however SFC typically utilizes carbon dioxide as the mobile phase; ther… bar miniatureWeb1 Mar 2024 · Chiral Stationary Phases: In chiral SFC, the CSP is the most critical parameter to achieve chiral resolution.
