Characteristic of Supercritical Fluid Extraction (SFE)

SFE is a sample extraction technique that uses a supercritical fluid (SCF) as an extraction solvent. SFE is also a separation technique in which one component (the extractant) is separated from another component (the matrix) using a SCF. The advantages of SFE technology are as follows (Lang and Wai 2001; Mendiola et al. 2007; Lee et al. 2012):
  1. (i)

    SFE provides high extraction efficiency and high extraction rates owing to the SCF physicochemical properties such as low viscosity and high diffusivity.

     
  2. (ii)

    Selective extraction of the target component can be easily controlled, because the solvating power of SCF can be easily regulated by changing the temperature and pressure.

     
  3. (iii)

    SFE is suitable for thermally and ox ...
