The 9th International Symposium on Packed Column SFC (SFC 2015) was held in Philadelphia, Pennsylvania, USA, on 22–24 July 2015. Selected highlights of both the oral and poster SFC 2015 programmes are reviewed in this synopsis.
Supercritical Fluid Chromatography (SFC) has been practiced for approximately 50 years. SFC on packed columns for both qualitative and quantitative purposes underwent a renaissance in interest at the beginning of the 1990s when limitations of capillary SFC became obvious and important progress in composition gradient techniques for mixed mobile phases was achieved. Even with these instrumental improvements, wide acceptane of the technology was not forthcoming because the perception was that highly polar analytes were not soluble in carbon dioxide and thus were not separable. It is now apparent that the use of additives dramatically extends the range of solute polarity amenable to SFC.
