Supercritical carbon dioxide drying problem

More recently, samples were dried with supercritical carbon dioxide, supercritical drying, and replacing the solvent in the sample with a gas. After drying, the sample was removed and the volume was reduced by 4/5. What is the reason?

Principle of carbon dioxide supercritical fluid extraction technology

The principle of supercritical CO2 fluid extraction (SFE) separation process is based on the relationship between the solubility of supercritical fluid and its density, that is, the effect of pressure and temperature on the solubility of supercritical fluid.

Technical characteristics of supercritical CO2 extraction

Extraction can be carried out at close to room temperature (35-40 ℃) and under CO2 gas cover, preventing the oxidation and dissipation of heat-sensitive substances. Therefore, all the components of medicinal plants are maintained in the extract, and the substances with high boiling point, low volatility and easy pyrolysis can be extracted below their boiling point temperature;
