17/8/2019, · SFC utilizes, a supercritical, gas,, most often, CO 2, instead of a liquid mobile phase to perform the separation. This means that the entire separatory column must be pressurized, and that the pressure inside must be monitored and regulated to ensure that the conditions required for reaching the supercritical point are retained.

26/6/2018, · Supercritical Fluid Chromatography is also a friend to our planet as it significantly reduces the amount of hazardous waste that often requires specific disposal methods. Another benefit is that there is virtually no dry down step required. 1 It is also an orthogonal technique to LC, meaning it typically appeals to those chemists who need a confirmation analysis within their workflow.

Then the eluent is made flow, and in the supercritical fluid chromatography (SFC) this contributes to the substances separation. In the case of the system SC CO2-oil, for example, at the operational temperature and pressure, the solvents is dissolved in the oil bulk, blowing it up and originating a Biphasic System , in which a CO2 rich phase is in the supercritical state, whereas the other, rich in oil, is liquid.

Supercritical CO2. The supercritical fluid commonly utilized is carbon dioxide (CO2). The state diagram of CO2 visualizes the various phases (solid, liquid, gas) depending on pressure and temperature. CO2, at 31,1°C and 73,8 bar, is in its supercritical state, in which there is no distinction between liquid and gaseous phases (as shown in the following picture).

Supercritical carbon dioxide - Wikipedia

Supercritical carbon dioxide (sCO 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 cooled and/or pressurised sufficiently.
