Supercritical fluid extraction hybrid

Hybrid Supercritical Fluid Extraction/ Enhanced Solvent Extraction... [Pg.123]

Principles and Characteristics In an attempt to develop a unified sample preparation system for extraction of various matrix/analyte combinations Ashraf-Khorassani et al. [498] have described a hybrid supercritical fluid extraction/enhanced solvent extraction (SFE/ESE ) system to remove both polar and nonpolar analytes from various matrices. The idea is that a single instrument that can perform extractions via pure C02 solvent, and all gradients thereof affords... [Pg.123]

Unfortunately, most polymers are insoluble in supercritical C02, and hence extraction from the ionic liquid by this method is difficult. However, if C02-soluble polymers were synthesized (for example, fluoropolymers and polysi-loxanes), then this method has the potential to be a very useful approach. Moreover, supercritical fluid-swollen ionic liquids offer a new solvent system that combines the viscosity-lowering properties of the supercritical fluid with the good solubilizing properties of the ionic liquid and may be a hybrid exotic solvent of the future. [Pg.340]
