摘要：

The separation of tocopherols by supercritical fluid chromatography with carbon dioxide as mobile phase using an ODS column was studied. The influence of operation temperature and pressure on capacity factor (k') and the selectivity (alpha) was investigated. It is found that the best operation condition for the isomers separation is at 343.15 K and 20 MPa.
