Whether you’re just looking to analyze chiral compounds or need to purify those compounds, Waters has the solution that fits your needs. This paper presents recent advances in Simdist using SFC of heavy fractions.

Download or order your copy today. Practical Approaches to Peptide Isolation. SFC excels at separating and purifying chiral compounds and natural products because it’s faster, uses much less solvent, and overall is a less phzse and greener method that exceeds high pressure liquid chromatography HPLC in performance for chiral separations. Thus, SFC could be the tool of choice for better determination of conversion in heavy petroleum-fraction processing.

Supercritical Fluid Chromatography : Waters

As a high pressure liquid, or supercritical fluid, using CO 2 is a smart solvent for its low viscosity and high diffusivity needed in today’s demanding purification labs and also a sustainable solvent as it is reused after being discarded from other industrial processes. On-Demand Webinar Available Now! The interest of supercritical-fluid chromatography SFC is that high temperatures are not needed to elute heavy ends and that the mechanism for extending the upper limit of simdist depends only on sample solubility into the supercritical mobile phase.
