For supercritical fluid chromatography (SFC), the mobile phase is generally of high diffusivity and low viscosity, which is achievable with the combination of a compressible fluid, usually carbon dioxide, and a normal liquid, such as methanol.Compared with HPLC, SFC with packed columns is 5-10 times faster than.In addition, its separation mechanism is similar to normal-phase HPLC since the mobile phase is less polar than the stationary phase.
