Packed column sub-and supercritical fluid chromatography (SFC) is a versatile separation
method: on the one hand the number of parameters acting on the quality of a separation is …

In the last few years, there has been a resurgence of supercritical fluid chromatography
(SFC), which has been stimulated by the introduction of a new generation of instruments and …

In the early days of supercritical fluid chromatography (SFC), it was categorized as high-
pressure or dense gas chromatography (HPGC or DGC) and low boiling point hydrocarbons …

The last 20 years have seen an intense interest in the use of supercritical fluids in separation
science. This started with the introduction of commercial instruments first for packed and …

The application of packed column supercritical fluid chromatography (SFC) for the
separation of polar analytes is reviewed. A comparison is drawn between the separation of …
