✦ Synopsis

Fused silica capillary columns with internal diameters from 100 to 25 pm werecoated withSE-54 and evaluated undersupercritical fluid chromatographic conditions using carbon dioxide as mobile phase.Experimental results compared well with theoretical predictions. At ten times the optimum mobile phase velocity and for a capacity factor, k of 3, efficiencies of 2300 to 5600 plates m-' were obtained for column diameters of 100 to 25 pm, respectively.

## Abstract An on‐line supercritical fluid extraction/capillary supercritical fluid chromatography system was developed using a capillary trap with stationary phase and a linear restrictor. With the system, samples can be injected into either the supercritical fluid chromatography (SFC) column or t

Packed capillary columns with low aspect ratios (column diameter/particle diameter, d,/d,) can be prepared by selecting the appropriate combinations of column and particle diameters. They provide lower pressure drops and higher permeabilities than columns with higher ratios. Therefore, longer column
