Abstract
Analytical-scale supercritical fluid extraction (SFE) of polar organics from solid samples was enhanced by derivatizing the analytes to less polar under static SFE conditions using reagents including trimethylphenylammonium hydroxide and boron trifluoride in methanol. After derivatization, the analytes were extracted with CO 2 using standard SFE techniques and analyzed without additional treatment using conventional capillary GC
