How Do Supercritical Fluids Work?
When a gas such as Carbon Dioxide is compressed and heated, its physical properties change and it is referred to as a supercritical fluid. Under these conditions, it has the solvating power of a liquid and the diffusivity of a gas. In short, it has the properties of both a gas and a liquid. This enables supercritical fluids to work extremely well as a processing media for a wide variety of chemical, biological, and polymer extraction.
