Supercritical-fluid chromatography (SFC) may be performed either in open (capillary) columns or in packed columns. Both approaches have been demonstrated numerous times in the literature. In this contribution it will be attempted to discuss some aspects of columns for SFC. Some advantages of both ty

## Abstract Packed capillary columns provide advantages of low flow rates, moderate sample capacities and loadabilities, short analysis times, high detectabilities, and the possibility of using a wide variety of commercially available stationary phases. This type of column is finding increasingly m

The adverse effects of injection solvent strength on microbore packed column SFC band broadening are demonstrated and a solventless injection system that eliminates these effects is introduced. The injection system removes solvent in a GC-like manner using a retention gap and an on-column capillary

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

## Abstract The supercritical fluid chromatographic behavior of polychlorinated biphenyls (PCBs) and polychlorinated terphenyls (PCTs) is described. The method uses a microbore C‐18 column and an open tubular capillary column coated with SE‐52 and carbon dioxide as the supercritical fluid. Factors
