Notes:
Fused-silica capillary columns with internal diameters of 50 μm were coated with 0.25 to 1.0 μm films of SE-54 and evaluated under supercritical fluid chromatographic conditions using carbon dioxide as mobile phase. Experimental results compared well with theoretical predictions. There was no significant difference in hmin or ūopt for film thicknesses from 0.25 to 1.0 μm over k = 1 to 5. At a film thickness of 1.0 μm, calculations indicate that approximately 10% resolution loss would be expected for solutes with k = 1.
