Waters SFx Systems use supercritical CO2 instead of an organic solvent. The supercritical fluid state occurs when a fluid is above its critical temperature (Tc) and critical pressure (Pc ). This supercritical state allows CO2 to take on the properties of a gas (high diffusivity, low surface tension), as well maintaining the solvent power of a liquid when it is between the typical gas and liquid states. Manipulating the temperature and pressure of CO2 alters the solvent power and allows the material of interest to be selectively extracted.
