Supercritical fluids, have ,properties, between those of a gas and a liquid. A ,supercritical fluid, can effuse through solids like a gas and dissolve materials like a liquid. All ,supercritical fluids, are completely miscible with each other, so for a mixture a single phase can be guaranteed, if the critical point of the mixture is exceeded.

Supercritical fluid chromatography - Wikipedia

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 ...

In the plastics industry, the diffusion of ,supercritical, CO 2 in polymers is accompanied by a swelling of these materials and a change for their physico-chemical ,properties,. ,Supercritical, CO 2 is a good plasticizing agent in particular because it reduces the glass transition temperature. The resulting polymer ,properties, are usually improved (resistance, thermal stability, purity).
