The separation of Eicosapentaenoic Acid(EPA)and Docosahexanoic Acid(DHA)-ethyl esters by supercritical fluid chromatography (SFC) with carbon dioxide as mobile phase using C18 columns was studied. The effects of flow rate
operation temperature and pressure
sample size and concentration on separation were investigated. It is indicated that the effect of flow rate on resolution is not obvious. As for 5-C18,250mm×4.6mm column
the optimum operating condition is 12MPa
55℃
pressure drop 1MPa; as for 8-C18,250mm×10mm column
the optimum operating condition is 12MPa
55℃
pressure drop 0.5MPa. Fish oil can been injected directly without dissolving in other solvents.
