A simple device for preparation of low concentration binary mobile phases in SFC

Determination of thermodynamic properties by supercritical fluid chromatography

“…The reason is a shifting vapour-liquid equilibrium as either phase is being drained from the tank. A simple method for preparation of cosolvent-modified CO 2 consists in saturation of the CO 2 stream with the cosolvent [242,243]. An obvious limitation of this technique is that it only yields a mixture of a single composition determined by the temperature and pressure in the saturator.…”

High resolution packed column supercritical fluid chromatography of fatty acid methyl esters

“…SFC on both open-tubular and packed columns has also been used for the separation of free fatty acids or their esters. Görner and Perrut [8,9] reported that the retention times of C 18 methyl esters from fish oils on silica or ODS-bonded silica columns increased with the degree of unsaturation. Higher retention times were found for 20 : 5 and 22 : 6 polyunsaturated esters.…”
