New Preparative Chromatography Learning Tool: SFC Primer
Beginner’s Guide to Preparative Supercritical Fluid Chromatography
Preparative chromatography continues to be an important purification tool in pharmaceutical, fine chemical, natural product, and other laboratory workflows. In recent years, many laboratories have also begun to include Supercritical Fluid Chromatography (SFC) as part of their purification strategies.
In an effort to help scientists better understand this technology, a new learning tool is now available. Written by Waters scientist Jacquelyn Runco, this primer “Beginner’s Guide to Preparative Supercritical Fluid Chromatography” introduces users to SFC, describes the technologies used in SFC analyses, provides practical tips and techniques, shows several practical examples from method development to scaling from analytical to prep.

“SFC is Chromatography!” –Jacquelyn Runco
As Jacquelyn enthusiastically writes, “SFC IS CHROMATOGRAPHY! Supercritical fluid chromatography (SFC) is a chromatographic technique that uses sub-critical (liquid) and supercritical CO2 as the primary solvent in the mobile-phase, usually accompanied by an organic solvent. Like all chromatography, SFC separates components based upon the partitioning of analytes between a stationary phase (column) and a mobile-phase (solvent).
“There are many similarities between HPLC and SFC, for example: SFC can be run using both isocratic and gradient method conditions and is compatible with all standard detection techniques such as ultraviolet (UV), photodiode array (PDA), evaporative light scattering (ELS) and mass spectrometry (MS). ’
“The general Prep SFC workflow is the same as for HPLC involving method development, scale-up, fraction collection and purity analysis of the collected fractions. It is also comparable to RPLC in terms of recovery and purity, for some applications recovery is better in SFC while for others HPLC is the better solution.”
