Some ,supercritical, fluids (e.g., ,supercritical, carbon dioxide) can be used to extract biological molecules (e.g., chlorophyll) from mixtures (e.g., ground up plant leaves). After the biological molecule has dissolved out of the mixture, the biological molecule is recovered by releasing pressure so the carbon dioxide returns to gaseous form, and drifts away.

Carbon dioxide is the most commonly used ,supercritical fluid, because of its low critical temperature (31°C), its inert properties, its low toxicity and reactivity plus its high purity and low cost. Carbon dioxide does not dissolve polar compounds, and so during the analysis of this type of compound, methanol, cyclic ethers , water or formic acid can be added to the carbon dioxide.
