Direct supercritical-fluid extraction of polycyclic aromatic hydrocarbons from aqueous solutions

Determination of organic impurities in pharmaceutical preparations

“…For the same purpose, nitrous oxide in the supercritical state can be used as the extractant. Of particular interest is solventless SFE, which was proposed in [41,42] and is used for the extraction of moderately volatile organic impurities from pharmaceutical preparations [43][44][45][46].…”

“…Some interesting applications of SFE also include determining tenside content in water [27], metals [28,29] and alkyphenols [30]. SFE can isolate weakly volatile substances from water and aqueous solutions too, for example PAH [31][32][33] and PCB [31,34,35].…”
