[0002] Supercritical is a supercritical fluid, which is a state of matter between gas and liquid that is neither gas nor liquid. This substance can only exist when its temperature and pressure exceed the critical point. The density of supercritical fluid is relatively large, similar to that of liquid, and its viscosity is closer to that of gas, making it an ideal extractant. The supercritical extraction device is a process that uses supercritical fluid as an extractant to extract and selectively separate target compounds. Generally, CO2 is used as a supercritical fluid. By changing the pressure and temperature of the extractant fluid, different components in the sample can be extracted in sequence according to their solubility in the fluid. Drugs usually require critical extraction.
