Supercritical Fluids Chromatography

The Supercritical Fluids Chromatography (SFC) is a kind of chromatography where the mobile phase is a supercritical fluid.
The most used SCF is the carbon dioxide (do not mix-up SCF SuperCritical Fluid and SFC Supercritical Fluid Chromatography).
Then SFC is a normal phase chromatography between the gas chromatography (GC) and the liquid chromatography (HPLC).
The systems are close to an HPLC but with a backpressure regulator to maintain the pressure above the critical pressure.
The stationary phase is in packed columns that can contain differents polar phases .

Update II: Natural Supercritical Water

I've found this video about the "Natural Supercritical Water"...

Supercritical Fuel System: 50-75% Improvement in Engine Fuel Economy

The TSCi gasoline fuel charge enters the cylinder at around 400 °C—compared to about 100 °C for a conventional liquid direct injection fuel charge—at precisely Top Dead Center (TDC, 0° crank angle).
The supercritical charge facilitates short ignition delay and fast combustion, with the energy released focused just on pushing the piston down. The fast combustion minimizes crevice burn and partial combustion near the cylinder walls, and prevents droplet diffusion burn.
