Both packed and open-tubular capillary columns are employed in supercritical fluid chromatography (SFC). The advantages and disadvantages of these columns in SFC have been discussed [l-31. Further discussions seem appropriate to predict which type of columns will survive in SFC. Fused-silica capilla

Abstract
Lubricating oil additives have been analyzed by supercritical fluid chromatography on open tubular and packed capillary columns. Carbon dioxide and modified carbon dioxide were used as mobile phases and detection was accomplished by flame ionization and micro UV. Rapid and efficient analysis of the lubricating oil additives was demonstrated.
