Separation of Ethanol-Water by Combination Process with Supercritical Fluid Extraction and Membrane Separation.

Rapid 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...

Mathematical Modeling of Gas Separation Process with Flat Carbon Membrane

Carbon molecular sieve membranes (CMSMs) have been considered as very promising candidates for gas separation, in terms of separation properties as well as thermal and chemical stability. Due to the numerous advantages and wide applications of carbon membranes, their application for gas separation is of special importance. Because of the importance of carbon membranes and a large number of stud...

Rapid Separation of Five Cyclosporin Analogs by Supercritical Fluid Chromatography

Recently there has been a resurgence of interest in cyclic peptides due to their therapeutic advantages in terms of potency, permeability, proteolytic stability, and unique selectivity relative to traditional smaller drug molecules. Cyclosporin is a family of cyclic peptides widely used as autoimmune suppression agents. Cyclosporin analogs consist of eleven amino acids with the main difference ...

Separation of Fischer-Tropsch Wax from Catalyst by Supercritical Extraction

Separation of Biomass Pyrolysis Oil by Supercritical CO2 Extraction

Supercritical CO2 extraction was employed to separate simulated and real bio-oils. Effects of extraction pressure, temperature and adsorbents on distribution coefficient (or enrichment coefficient) of five representative compounds were investigated using a simulated bio-oil, which was composed of acetic acid (AC), propanoic acid (PA), furfural (FR), acetylacetone (AA) and 2-methoxyphenol (MP). ...
