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
Direct analysis of polar solutes by supercritical fluid chromatography (SFC) has been somewhat limited because the mobile phases in common use are all relatively nonpolar. Derivatization is demonstrated as a viable means for facilitating the SFC separation of sugars. Oligo-and polysaccharides contai
## Abstract The separation of the geometric isomers of chromium and rhodium chelates of trifluoroacetylacetone and thenoyltrifluorβoacetone was investigated using packed column supercritical fluid chromatography. Mobile phases consisting of neat and alcoholβmodified carbon dioxide were used, and th
