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.
