   8 lut 2020 · Reversed-phase supercritical fluid chromatography (RP-SFC), which can be achieved with a non-polar C18-bonded phase, is an interesting alternative for the separation of this type of non-polar compounds. With regards to the organic solvents used in NARP-LC, carbon dioxide has many advantages: ecological, economic and physico-chemical.
