Learning Objectives To understand the basics of a onecomponent phase diagram as a function of temperature and pressure in a closed system To be able to identify the triple point, the critical point, and four regions: solid, liquid, gas, and a supercritical fluid

Supercritical fluid Wikipedia

A supercritical fluid (SCF) is any substance at a temperature and pressure above its critical point, where distinct liquid and gas phases do not existIt can effuse through solids like a gas, and dissolve materials like a liquid In addition, close to the critical point, small changes in pressure or temperature result in large changes in density, allowing many properties of a supercritical

Supercritical Fluid Chromatography an overview

Supercritical fluid chromatography encompasses all chromatographic methods in which the mobile phase is supercritical under the conditions of analysis, with the solvating properties of the fluid having a measurable effect on the separation The physical state of these conditions are illustrated in Figure 6 for CO 2, the most commonly used supercritical solvent

Supercritical carbon dioxide Wikipedia

Supercritical carbon dioxide (s CO 2) is a fluid state of carbon dioxide where it is held at or above its critical temperature and critical pressure Carbon dioxide usually behaves as a gas in air at standard temperature and pressure (STP), or as a solid called dry ice when frozen If the temperature and pressure are both increased from STP to be at or above the critical point for carbon
