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

## Abstract It is often observed that peak area precision in packed column supercritical fluid chromatography (pSFC) is rather poor when compared to values obtained in HPLC. Since the valves used for sample introduction in both techniques are identical, it is reasonable to expect that injection pre

A versatile system with a slurry-packed capillary column was developed for supercritical fluid chromatography, which is capable of programming both inlet and outlet pressure independently, as well as using a restrictor to apply back pressure. This system revealed the relationships between pressure d

## 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

## Abstract Packedโ€column supercritical fluid chromatography (pSFC) is a fast separation technique that combines the properties of HPLC and GC. pSFC with carbon dioxide as the mobile phase and packed silica column as the stationary phase possesses the properties of normal phase mechanism; however,
