For laboratories overwhelmed with solvent disposal and time-consuming solvent cleanup, supercritical fluid chromatography SFC is a beneficial alternative to purification and analytical applications. Considered a leading “green” purification technology, SFC systems from Waters are used to separate and chromatograpyie chiral and achiral chemical compounds using various methods of detection.


Previous article Next article. Dahan 1D. The interest of supercritical-fluid chromatography SFC is that high temperatures are not needed to elute heavy ends chromatgoraphie that the mechanism for extending the upper limit of simdist depends only on sample solubility into the supercritical mobile phase.

On-Demand Webinar Available Now! We ask, “how’d you do it? In which subject field? Lessons from Newborn Screening Simulated distillation simdist based on separation using gas chromatography GC is widely spread in the petroleum industry for evaluation of fossil fuels as well as petroleum feeds and cuts produced by refining and conversion processes.

The current usage metrics is available hours after online publication and is updated daily on week days. Increase detection selectivity and confidence using mass detection.

SFC excels at separating and purifying chiral compounds and natural products because it’s faster, uses much less solvent, and overall is a less expensive and greener method that exceeds high pressure liquid chromatography HPLC in performance for chiral separations.

Metrics Show article metrics. The principles of SFC are similar to those of liquid chromatography, however SFC typically uses carbon dioxide as the main mobile phase. Material Safety Data Sheets. The mobile phases used in SFC are gases such as freon, ethylene, or carbon dioxide. 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.

SFC is essentially a normal-phase chromatographic technique with inherent high speed and efficiency due to its mobile phase. Thus, SFC could be the tool chromatographue choice for better determination of conversion in heavy petroleum-fraction processing. Once the optimal mobile phase and stationary phase are determined from screening, the method can be easily scaled for purification on the same system.
