COSMOSIL Cholester
COSMOSIL Cholester / Cholesteryl group
Supercritical Fluid Chromatography (SFC) has become more attractive because it offers some advantages over HPLC, such as high speed, unique selectivity and environmentally friendly separations. Many conventional normal-phase stationary phases, such as diol, amino and cyano, have been used for SFC applications. However, these phases present limitations for separations. COSMOSIL SFC Columns have been developed to enhance the capability of SFC separations.
| COSMOSIL Cholester | |
|---|---|
| Silicagel | high purity porous spherical silica |
| Average particle size | 2.5 and 5µm |
| Average pore size | approx. 120Å |
| Specific surface area | approx. 300m2/g |
Application: Fat-Soluble Vitamin Analysis
COSMOSIL Cholester exhibits strong retention for fat-soluble vitamins and is suitable for on-line SFE-SFC using Shimadzu’s Nexera UC. The on-line extraction from food also produced triglyceride impurities, which were successfully separated from the
vitamins.
