✦ Synopsis

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 capillary tubing with an immobilized stationary phase has been commonly employed as the open-tubular column, and various type of stationary phases are now commercially available. On the other hand, packed columns for high-performance liquid chromatography (HPLC) are also employed in SFC. This paper describes the applicability of a glass capilary column treated with an alkaline solution to SFC.
