摘要：

The principles of the application of supercritical fluids in extraction and chromatography are discussed. The influence of fluid density on solvation properties is described. Because of its non-toxicity and convenient critical properties carbon dioxide is an unique fluid for extraction. The chromatographic behaviour is depending on viscosity and solute diffusion coefficients in the fluid. Supercritical fluid chromatography is compared with liquid and gas chromatography in respect of achievable efficiency.
