Drug Nano-Particles Formation by Supercritical Rapid Expansion Method; Operational Condition Effects Investigation
Dissolution pressure and nozzle temperature effects on particle size and distribution were investigated for RESS (Rapid Expansion of Supercritical Solution) process. Supercritical CO2 was used as solvent and Ibuprofen was applied as the model component in all runs. The resulting Ibuprofen nano-particles (about 50 nm in optimized runs) were analyzed by SEM and laser diffraction pa...

متن کاملRapid peptide separation by supercritical fluid chromatography.
BACKGROUND Supercritical fluid chromatography (SFC) is continually gaining attention in the separation sciences as demand increases for higher throughput isolations and purifications. The higher flow rates associated with SFC provide a significant decrease in analysis time and increase in sample-throughput efficiency. Peptides are of particular interest for SFC due, in part, to the rather exten...

متن کاملParticle Formation by Supercritical Fluid Extraction and Expansion Process
Supercritical fluid extraction and expansion (SFEE) patented technology combines the advantages of both supercritical fluid extraction (SFE) and rapid expansion of supercritical solution (RESS) with on-line coupling, which makes the nanoparticle formation feasible directly from matrix such as Chinese herbal medicine. Supercritical fluid extraction is a green separation technology, which has bee...
